User questions & answers

Question:	Can I use this with a microbit
Answer:	I am not familiar with the litemyfire so I can not compare. These rods are approx 3" long with the thickness of a pencil. They come in a really nice container with loops. Container can work as a great tinder box as well.
Question:	Can i hook this directly to the item i want to switch? it’s dc current
Answer:	The material of the 2 products is the same. The big one is easier to get sparks because of more interface with scraper. However, if you believe your scraper is excellent, you can also get tons of sparks from the small rods. The blade of an art knife is a good scraper. Check out our video of the 1/2 rod: https://youtu.be/3EtjPNZnwFQWe'll post a video of the small rods soon later. Please subscripe our channel.
Question:	How would you describe the range and sensitivity of these? I need to detect when motion stops in a 12x14 room of people
Answer:	I would venture to say that they are much too large for that. Besides, there is only one hole on one end, you'd need one on each end to properly hold it in place. For what you want to do, I'd recommend checking these out: https://www.amazon.com/bayite-Survival-Drilled-Paracord-Bracelet/dp/B00PSGOH3C/ref=sr_1_1?s=sporting-goods&ie=UTF8&qid=1484308685&sr=1-1&keywords=Flint+stick+drilled
Question:	Is the sensitivity adjustable
Answer:	No,they come in a plastic bag and that bag is put into a bubble-pack envelope. I think they are a great value.

Product features

HC-SR501 PIR Sensor Sensitivity and Time Delay is adjustable

There are two potentiometers onboard.

One is to adjust the sensitivity, and the other is to adjust delay time.

Also there are two trigger mode. One is Single trigger mode, which means that delay is started immediately upton detecting motion, and continued detection is blocked. The other is Repeatable trigger mode, timely delay is re-started every time motion is detected.

User questions & answers

Question:	Will this illum a led and send to a ext dev for when ir strikes reflective tape or connection is interrupted. I have 5 to 15 volts 150mA
Answer:	Hello Jason: I think the question you are asking is: Can this device be used to trigger an L.E.D. by sending a signal to an illuminating circuit (i.e. switching circuit) if and when the built-in Infra-Red led transceiver's reflected beam is broken or interrupted by an object or obstacle placed in the path? Is my assumption correct? If so, then yes it is possible to perform this task with this device as the sensor/activator front end to either the Arduino (for processing) or an adequate momentary logic circuit and an IR reflector designed to make this happen...Kind of like an "electric-eye" type of intrusion detecting device. Hope this helps.
Question:	Will these work with a Raspberry pi
Answer:	The quick answer is YES, they will. The longer answer is BUT, there are not that many I/O pins on a Raspberry Pie so it would be easy to use up your pins with just a few of the IR devices. So possibly a analog or digital multiplexer would allow you to use say 8 of the IR devices using 3 output pins to select which IR unit you wanted and a pin to read the value of the IR device. There maybe some Raspberry hats that have this kind of thing all figured out though.
Question:	Will this work for a 24 volt solenoid
Answer:	These devices, by themselves, will not handle a 24 volt ac or dc solenoid. The output of these devices is strictly a T.T.L. or RS-232C level. You might want to interface a trigger interface that could handle the current involved, to do the job; which could easily be done. But the answer to your question is no, they cannot by themselves handle 24 volts. Hope this helps.
Question:	What is the repeatability of these sensors? I'm trying to use them to measure length
Answer:	You can't measure length with these sensors. They are photo-switches. The emitter reflects off the surface back into the photo-diode. You set the level at which the photo-diode meets the comparator threshold by way of potentiometer on the sensor. So how "repeatable" is the sensor - fairly under ideal conditions. You can detect the position of an object to a few millimeters repeatably, but the "repeatability" is affected by a number of other factors:1. Distance - as the distance increases the reflected light decreases (as a square of the distance - both out and return) so the sensitivity wrt distance drops. 2. Emissivity of the surface - it has to reflect the IR ligth afteral3. Angle of the surface relative to the transmitter - a smarter man would say something about solid-angles4. Ambient light - probably the worst gremlin, especially as distance increases and you drop the sensitivity. In my experience, when you get out past 20 cm, sig/noise goes to hell outdoors.5. Direction/speed object is moving - There is a bit of a hysteresis, We've never noticed any timing delay, but YMMMV.I'm sure there's more, but you get the idea.

User questions & answers

Question:	What is the pinout on the ir receiver led. No documentation provided
Answer:	yes
Question:	Why would they include and ir led transmitter? does they remote have one installed on top already (and much smaller too
Answer:	The inseam in a size 5 is 18 IN and the inseam on a size 6 is 19 IN Victoria-Lollytogs
Question:	Why is there a LED included
Answer:	I don't think they look obviously boys. When my son grows out of them his little sister wears them if they are not too worn out. She looks fi e.
Question:	Does this work with an Arduino Uno
Answer:	No, just the back is elastic. Victoria-Lollytogs

• Can be used for 3-5V DC power supply modules. It has red power indicator.
• IR Infrared Obstacle Avoidance Sensor Module can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on
• The output port OUT sensor module can be directly connected to the microcontroller IO port, you can directly drive a 5V relay
• It has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing, green indicator will light up, at the same time signal output interface to output digital signal (a low level signal).
• Packed with high quality box.

User questions & answers

Question:	what is the distance detection range
Answer:	Yes, since our products use 110V US plugs, you can plug it into a US universal power strip .
Question:	what is the size of the PCB
Answer:	It would get damaged! it is not strong enough to be taken on an airplane.
Question:	Is it compatible with Raspberrypi
Answer:	This sauna allows one person (an adult) to sit in it.
Question:	The output port "OUT" supplies 5 volts at what current
Answer:	Roughly 3/4 of an inch. Mines came damaged but measuring the area that wasnt damaged. And the net connections is 1” fits a little big n wobbly tho.

Product features

Product Specification:

• The output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay ;
• The module detects the distance 2 -30cm, detection angle 35 °, the distance can detect potential is adjusted Can be used for 3-5V DC power supply modules
• When the power is turned on, the red power indicator light
• Using the comparator LM393
• Interface :
• 1. VCC: External 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU)
• 2. GND: GND External
• 3. OUT: Small board digital output interfaces (0 and 1)

Warm tips:

The light sensor module have strong adaptable to the environment, having a pair of infrared transmitter and receiver, transmitter launch a certain frequency infrared, when meet obstacle in the detection direction, the infrared receiver is reflected back by the receiver tube, after processing through the comparator circuit, the green indicator light will illuminate while the signal output interface output digital signal (a low-level signal) can be adjusted via potentiometer knob detection distance, the effective distance range 2 ~ 30cm, working voltage is 3.3V-5V. The detection range of the sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used robot obstacle avoidance, obstacle avoidance car assembly line count and black-and-white line tracking and many other occasions.
