This project creates an ESP32-based generic dual relay controller using Espressif RainMaker that can control two independent relays remotely. The implementation is based on the ESP RainMaker switch ...

This project allows you to control your cars lock system, to lock or unlock your car doors from nearby using a remote as in a normal car alarm system and if the remote is out of range you may send an ...

This design idea outlines a method to use an analogue switch and discrete components to reduce the power dissipated in relay actuation. Presented here is an MAX4624-based circuit to drive a 5V relay ...

Abstract: Remote controlling of home automation system has the potential to help people to control the electronic and home appliance from anywhere. Internet of things (IoT) is proposed to provide the ...

This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...
