We have built a very simple Motion detector circuit here. We are using a HC-SR501 PIR Sensor, an LED (which will glow whenever there is a motion infront of the sensor) and resistor. PIR Sensor Based ...

Motion sensor circuit Fig. 1: Circuit of motion sensor for security light. The working of the circuit is simple. When you power-on the circuit after assembling all the components including the CFL, ...

Fig. 1: Circuit diagram for Motion Activated Tap Water Flow Circuit. Before understanding the working of the project, let us understand the workings of the PIR motion sensor, which is the heart of ...

IR sensor Module. Components. IR pair (IR LED and Photodiode) IC LM358; Resistor 100, 10k, 330 ohm; Variable resistor – 10k; LED; You can see the connections in the IR sensor circuit diagram. Photo ...

A HomeKit firmware for an esp-01s pcb with an infrared motion sensor HC-SR501. This uses an over the air (OTA) mechanism create by @HomeACcessoryKid - lizzus/esp01s-homekit-motion-sensor ...

A fully self-sustaining, solar-powered motion sensor light system built around an ESP32. It features deep sleep modes, RTC-based nighttime detection, and a PIR sensor to only activate when ...

This article presents a new low-cost PCB-based accelerometer. A metal film is adhered to PCB board, which forms the two electrodes of the sensing capacitor of the accelerometer. The sensor signal is ...
