The system gets activated when someone passes through the gate to interrupt the IR beam falling on the sensor. IR-based Light Control Circuit IR based light control: Transmitter circuit ... As a ...

This project demonstrates a smart relay system that can be controlled using the Blynk mobile app. The relay can be operated based on inputs from a proximity sensor (infrared sensor) and a clap (sound ...

Circuit operation. Circuit diagram of the IR motion sensor relay switch is shown in Fig. 2. It is built around a PIR motion sensor module (connected across CON2), MOSFETs BS170 (T1) and IRF9540 (T2), ...

Circuit Diagram: Relay module: Connect the IN pin of the relay to a GPIO pin (e.g., D1 or GPIO5). ESP8266 or ESP32: Make sure the relay module's VCC and GND are properly connected to the board.

Demonstration of Motion Sensor Circuit. By following the 555 timer motion detector circuit diagram given above, I created the circuit on perf-board, the video of which is available at the end of the ...

Sonoff TH16 is a WiFi relay device powered by Espressif ESP8266 WiSoC, able to handle a load up to 16A (3500Watts @ 220V), and including a jack for sensors. The company recently sent me a sample ...

Testing our Solid-State Relay . The circuit is connected with the ESP8266-01 with a 3.3V power source. Also, a 100-Watt Bulb is used for testing purposes. As you can see in the above image, I have ...

The devices used are impulse indicator LED on kWh Meter which can be censored by LDR every time the LED blinks, relay as remote control switch via the internet, NodeMCU ESP8266 as processor and sender ...
