We will begin by understanding the actual PIR sensor unit which are installed insidestandard PIR modulesand learn its internal characteristics, pinout details and internal working details. What is a PIR Sensor? PIR stands for Pyroelectic Infrared Radial Sensor or Passive Infrared Sensor. PIR is an ...
MQ sensor working principle involves detecting changes in electrical conductivity when specific gases come into contact with the sensor’s sensing element. This variety of semiconductor gas sensors makes it possible to measure concentrations of gasses such as alcohol, methane, propane, butane, and ...

ESP32-CAM takes a picture, save it on the memory card and cut off the power so only the PIR sensor remains active. I need a external circuit to do this. The SR-602 sensor output signal is 3.3v for only about 2.4 seconds (not modifiable). If I use a transistor like a switch, ...
PIR Sensor Most PIR sensors have a 3-pin connection at the side or bottom. One pin will be ground, another will be signal and the last pin will be power. Power is usually up to 5V. Sometimes bigger modules don’t have direct output and instead just operate a relay which case there ...
