20141222· I''m trying to use a Panasonic AMN33111 digital output PIR sensor to trigger a device. The device is triggered by grounding a 3v signal line. The AMN has an active high output line. I was able to prototype the behavior I want using an mbed dev board, but I''d like to try and wire this using just a transistor. I''ve tried using several NPN transistors (BU806 and BU408) …
tric Infrared Sensor can detect this infrared radiation and convert it to an electric charge. This charge is buffered through a FET and can be converted to voltage variations using a load resistor.

20151130· First of all, a PIR sensor is not a transistor, although the packaging may be similar in some cases. Secondly, the output of a PIR sensor is an AC signal, based on the changes in thermal energy it is receiving, not its absolute value. These changes are enhanced by using optics (usually a Fresnel lens of some sort) to project multiple "zones" onto the sensor, and the output signal is caused …

20180112· A PIR Sensor or a Passive Infrared Sensor is an electronic device that measures the infrared (IR) light emitted by the objects in its observable area. The term ‘Passive’ in the PIR Sensor indicates that the sensor actually doesn’t emit any infrared light but rather passively detects it that is emitted by its surrounding objects. Every object, with its surface temperature …
