PIR（Passive Infrared Detection）are used to detect motion of human movement. This version has a large lens which can support long range and wide angle. 2.54mm standard connector is easy to fix it ...

I try to make the PIR sensor module without using the commercial IC which has all the functionality such as normal-mode, re-triggering and turned on only at the dark environment. This is very hard to ...

The Amplifier IC is used to amplify the Output from Dog Barking Sound Module. The Alarm circuit consists of an Arduino Nano, PIR Motion sensor, LM386 Amplifier IC, Speaker, NPN Transistor, and a ...

Whenever the PIR module detect movement of a live body its relay output toggles and the switching mosfet (T1) in the circuit is switched to on via resistor R1 and related parts.

This is a simple update to Mr. Hareendran’s PIR Sensor Security Light circuit. It has a shortcoming limits the relay voltage to approximately 3.3V. While this may function with some 5V relays, it will ...

As advanced as this sounds, it can be accomplished easily using a cheap sensor called the RCWL-0516. RCWL 0516 Module The RCWL-0516 Microwave Radar Sensor module has been designed as an alternative to ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

The integration of the PIR sensor in the module enables a wireless solution with low electromagnetic interference (EMI) characteristics. The PIR sensor’s wake-up feature is important for ...
