Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Working Voltage:DC 2.7V-12V;Max Static current:1mA;delay time: 2S;Blockade time: 2S;Sensor angle:100 Degree;Sensor distance: 3-5m. Repeatable Trigger Mode:When people enters the sensing range, the ...

Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

Trumpeted as the world's smallest pyroelectric infrared (PIR) sensor, the IRS-B210ST01-RI measures 5 mm x 4.7 mm x 2.4 mm. The component is also said to be the only surface-mount PIR sensor available ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...
