• This is a high-precision digital air pressure sensor, integrated with BMP388 chip to achieve data tracking accurately, Monitor atmospheric pressure and temperature, support I2C/SPI interface, and compatible with 3.3V/5v voltage.It compatible with Raspberry/Arduino/STM32 and other motherboards.
• The BMP388 digital pressure sensor is a very compact 24-bit sensor with low power consumption and low noise. The sensor offers a best-in-class temperature coefficient offset (TCO) between 0 Degree Celsius and 65 Degree Celsius for accurate height measurement over a wide temperature range. The digital sensor has low power consumption, only 3.4μA at 1Hz, and a wide measurement range from 300hPa to 1250hPa.
• for flying toys, drones, handheld devices, such as mobile phones, tablets, GPS devices, navigation systems, portable health devices, home weather stations, watches, white goods and other application scenarios.
• Note: The altitude calculated by the air pressure sensor is generally used as a relative value in a short period. For example, when taking a vertical elevator, record a height before the elevator starts, and the elevator rises to the 3rd floor, and records a height. The height difference between the two heights is accurate.
• If you need to use it in absolute situations, you can enter the height of the current position as the initial value of the calculation, and then exercise to observe the height change is accurate. However, if the time is long, the problem of height drift will easily occur. If the project requires long-term acquisition of accurate altitude values ​​and high frequency requirements, it needs to integrate other sensors for processing, such as GPS.

User questions & answers

Question:	What’s its maximum height reach
Answer:	Yes, you can install multiple cameras on the same account. I have 4
Question:	Does it have a return home feature
Answer:	Continuous recording is available if you insert an SD card. Activity Detection Recording is optional in the settings. When you turn on Activity Detection Recording is turned on, you lose continuous recording, but you will get the short clips on an easy to read list to easily watch. The main way to watch the continuous recording is to tap on your live view screen and a timeline below will appear. Scroll to the time you would like to watch.
Question:	What is a 4g tf card? i searched both amazon and microcenter and got back some pretty sketchy results
Answer:	It is an app...or website option... ie it can be hacked... anything wifi/ip can be viewed by anyone inside the company that "services" that device... you can pay for your access to view/record, but it is still viewable by the company and government agencies.
Question:	Sd card included in
Answer:	You used to be able to access recorded content since the cameras have SD cards. Now you can only look at six seconds of footage without subscribing to their cloud service. We bought all six of our cameras before they changed this policy. Now they’re worthless without the cloud service. I won’t, on principle, subscribe to the service since I don’t believe this sort of extortion should be rewarded.

User questions & answers

Question:	Just wondering if this is the 203F or the 203M model, picture is of 203F, however model # is not specified. Thanks
Answer:	No. It's designed for flying things. Technically, you could put it in realtime mode, and see how the elevation CHANGES (higher or lower) from when you turned it on, but it's not really designed to be a dashboard altimeter. If you did decide to use it in your truck despite this, you'll want to get the snap mount to keep it classy. "Duck" tape is not the way to go when it comes to mounting a flight altimeter in your pickup.
Question:	Do you have to adjust this altimeter periodically to get an accurate reading
Answer:	This altimeter is really not designed for hiking, so I would not advise that you buy it for that (it's a flying altimeter). By the way, I'm the designer.Other answers are correct: it will show altitude change (when in Realtime mode) since it was started. But on a hike of any decent duration, the weather may change, perhaps as much as 20-50 feet as a high or low pressure front moves in. So over the course of hours, you would have to factor that in. It's really designed for short (
Question:	where is this product made
Answer:	Yes you can have feet or meters however feet is more accurate, if you need that, and then just multiply it by 0.3048 to get meters.
Question:	Can this be used in Nepal or other 3rd world countries
Answer:	Don’t know, haven’t had it below sea level yet.

User questions & answers

Question:	i saw the video on tthe site and was wondering is there a certain type of camera, i would need to purchase for this? thanks, james
Answer:	Not easily - the pump is on the input end of the intake hose and the auto-shutoff sensor is at the output end of the discharge hose... both the hoses and the wiring inside of each hose would have to be extended and sealed.
Question:	Will multiple motors give false readings
Answer:	This product never worked for me. I purchased it to transfer fuels to equipment. The hoses might be easy to clean, but the pump would be impossible. Any milk left in would quickly sour and spoil the next batch. Its non-repairable, so save your money and avoid the Chinese products.
Question:	How long will an AltimeterThree run on a single charge
Answer:	You don't need gravity, it will draw out of the gas can. What you do need to be aware of is, after it automatically shuts off (if you have it set up properly) you may still have some gas left in the clear hose of the pump. All you have to do at that point is to either allow the gas to flow into the tank your tying to fill or back into the can that your pumping from. This is because once the pump shuts off, there will be gas still left in the hose. Just raise the hose up to empty into the tank or raise it higher than the gas can your pumping from and it will empty back into that can. It's actually very simple to do but not as simple to explain. Bottom line is that I'm very pleased with this pump, I have a 5 gallon can connected to it on a shop cart and I just wheel it over to what needs filling and it's great!
Question:	Any data on accuracy? I’m not too picky but it would be good to know the expected error range
Answer:	No. Not enough pressure nor will it pull the water from the bottom of your tank. Best bet is some kind of pond pump or larger.

User questions & answers

Question:	does it work with google home hub or lenovo smart display
Answer:	Mines doesn't work with Google home hub
Question:	Do both of these cameras come with an SD card
Answer:	Memory Card it's not included, it's compatible with memory cards up to 32GB. I bought this > http://topreviews24.com/micro-sd-card/samsung-32gb-evo-select/
Question:	Will this work pointed out through a window or will it glare at night? Any suggestions to block the glare? One area only inside window is an option
Answer:	I have two of my cameras pointed through my windows. One in front and one in back of house. As long as there is lighting, it will not glare. When it is very dark, there is a glare. I put out 2 small solar lights in the backyard and turned off the night vision and absolutely no glare ever since. No glare issues in the front of the house as the neighborhood is well lit.
Question:	Has anyone used it for at least 6 months? Is it good to capture a thief in a home? What is its connectivity and alert system in case of a thief
Answer:	A lot of feedback here already, but I’ve had at least one Wyze camera in my home for about a year now and in my experience, they are better than my Ring devices in terms of connectivity and alerts. They connect in the app within 10-20 seconds and the Person Detection is great. I highly recommend the service which extends the recording time as it’s cheap but makes their devices that much more of a premium product. 10/10

User questions & answers

Question:	I have a pro-2000. after factory servicing it gave inconsistent readings even after recalibration. has anyone had this experience? options
Answer:	I would say no. The two gel-cell batteries in the unit are 12v each, and either 7 amp hour or 9 amp hour, depending on replacement battery specs. Typical deep cycle 12v batteries produce about 48 amps, and you would need two for the required 24v input. It would be best to contact Eaton and ask one of the engineers.
Question:	Mine is still working after 4 years but says "cord" on screen at times..what is that
Answer:	As long as the battery is charged yes. Don’t forget to hook battery up when you first get it.

User questions & answers

Question:	Does the 78sc include the Great Lakes coastal areas
Answer:	Hi Thomas,Since I just have the 78 I'm not sure. With the 78 I bought the micro card that gives me maps of all US, Canada, some Bahamas and Mexico. The original GPS without the card gave only a no detail sketch of landmasses. with the card, it does show depths and boys of the great lakes areas. According to the west marine catalogue, the SC comes with the chart I bought preloaded, which is a really good deal. Had I realized I would be buying the chip, it would have made more sense to get the SC. I'm thinking about adding the chip with topographic features for land travel. http://www.westmarine.com/buy/garmin--gpsmap-78sc-marine-handheld-gps-receiver-with-compass-and-barometer--11553609

User questions & answers

Question:	how do i know if I have bluetooth on my pc
Answer:	You can contact us by email after purchasing this item,we'll send you the data file.
Question:	can I get report on a computer that is blue tooth compatible
Answer:	Note: The altitude calculated by the air pressure sensor is generally used as a relative value in a short period. For example, when taking a vertical elevator, record a height before the elevator starts, and the elevator rises to the 3rd floor, and records a height. The height difference between the two heights is accurate. If you need to use it in absolute situations, you can enter the height of the current position as the initial value of the calculation, and then exercise to observe the height change is accurate. However, if the time is long, the problem of height drift will easily occur. If the project requires long-term acquisition of accurate altitude values ​​and high frequency requirements, it needs to integrate other sensors for processing, such as GPS.
Question:	Does it give a hrv reading
Answer:	I returned mine. Various problems.
Question:	Does the app cost money
Answer:	Yes it should. Make sure the battery is connected.
