User questions & answers

Question:	What do these sensors do? What do they react to
Answer:	I have 4 of the blue chairs, the color is not teal or navy. The photo is almost exactly how it looks in person.
Question:	Can the sensor range be adjusted
Answer:	I wouldn’t say they would be too small, and they are comfortable enough to sit and talk. This is definitely not a lounging chair, or binge tv chair. We have four of them in our office, for customers, so they do not get a lot of continuous use like that. They are great looking and get a lot of compliments.
Question:	How can you tell which prong is ground, neutral or hot
Answer:	They are definitely more for looks. Comfy isn’t a word I would use to describe them. I’m 5’8”. It is definitely a nice chair though.
Question:	How long do these supply power after triggering
Answer:	It's faux velvet. The chair pad has a zipped cover that can be removed.

User questions & answers

Question:	Do i have to add arduino or will it turn light on/off by itself? How long will light stay on
Answer:	Yes, you can, but you need correct cable , female dupont cable with Alligator Clip Test Lead
Question:	Does this product have an actual spec sheet with clear dimension
Answer:	WRCoyle is pretty much wrong on their answer. I'm assuming you want to turn electricity on to another device with this? The answer to that is no. This provides a logic output that is high when it is triggered and low when on standby. The BISS0001 chip on this has the output pin rated for 10mA and it goes straight to the out pin on the board, no transistor used to handle more power. It can run a regular LED using a resistor to limit the LED to 10mA or less. Beyond that, you will need a transistor or solid state relay or some other setup to handle any amount of current.
Question:	how do you wire this thing
Answer:	It will sense any movement (heating moving paper) in a room of that size
Question:	Any way to change the delay time
Answer:	Yes there are two pots on the board you can use to adjust. Check the web for how to do it.

• ♥ Automatic Induction. The light will be activated ON/OFF by auto PIR motion detection. Motion sensor can identify day and night automatically.
• ♥ Infrared sensor switch utilizes human motion infrared rays as control signal sources, when one enters the detection field, it will start the controlled load at once.
• ♥ Energy-saving and low heat and low power consumption. Motion sensor turns lights ON automatically when motion is detected and OFF after a pre-selected time delay (5sec to 6minutes).
• ♥ People can enter the sensing range and can be automatically turned on,When people leave, they can automatically delay the shutdown, so as to prevent the conventional lamps from being opened.
• ♥ We strive to provide you with high quality and convenient service. You are welcome to contact us if you have any problem about our product, we will give you a satisfactory reply.

User questions & answers

Question:	Is it possible to eliminate any delay, so the trigger is almost instantaneous
Answer:	When these sensors say "delay" it means how long the sensor stays in its "on" state after being triggered. So having a 2 second delay means that when motion is detected, the sensor immediately goes to its "on" state and stays "on" for 2 seconds after the motion is detected. There is do delay in detection.
Question:	How much output current will it handle
Answer:	It cannot directly drive very much. It would need to be boosted with some sort of driver, a transistor or something else that can handle more current. I doubt that the output can drive more than10ma. The output will be the same voltage that you supply the device with, but the amount of current it can handle is small.
Question:	Does anyone know the max out current? Thanks
Answer:	It does not exactly say, but the mention that is for "Internal use of digital signal processing" this implies that it supplies a voltage for a digital Input, but low current. Additional components such as Transistors or MOSFETs could be used to increase the current if you want to direct drive something.
Question:	Can i wire these in between 5v led strip lights and 5v usb output
Answer:	I assume you are wanting to use this to turn on and off your led lights. you can use it as a trigger to turn them on but it can not power them directly. You would need a relay or MOSFET that can take a control signal.
