Webb23 mars 2014 · That PIR module is a raw PIR sensor connected in a general purpose op-amp circuit, provided by a LM324 series quad operational amplifier. One way of increasing the sensitivity is by changing the value of a resistor or capacitor in one of the op-amp stages. This could lead to over-sensitivity, and false positives. It depends on what values … WebbDescription. The PIR-130 module includes a 1-channel passive infrared (PIR) sensor that is able to detect infrared waves generated by human within a range of approximately 8 meters in diameter with a 360° coverage area. The PIR-130 is used for indoor motion detection, and can be configured to automatically switch on a light if motion is detected. girlshort https://myorganicopia.com
