The size and price of the ESP wifi modules have quickly made them into one of the preferred building blocks for IoT devices. Unfortunately they are not particularly well suited for very low power ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

This project demonstrates a simple motion detection alarm system using a PIR sensor, an LED, and a buzzer. When motion is detected, the LED and buzzer are activated for 2 seconds to indicate movement.

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

Figure 1 shows a way to control a light (or other 120-V ac appliance) with a passive-infrared (PIR) alarm sensor. The original concept was to turn a closet or shop light on whenever someone went into.

This light-weight (1.4kg) flood light, GL-FL30S-V2, provides bright and pleasing illumination suitable for indoor and outdoor retail, commercial and industrial external lighting applications. When ...
