The ESP01, powered by the ESP8266 IC, is a popular choice for IoT projects due to its compact size and integrated 2.4GHz WiFi capabilities. However, this isn’t just the ESP01 module itself; it’s a plug-and-play relay module designed for use with the ESP01.
This relay module allows you to control AC or DC loads, handling up to 250V AC at 10A. It conveniently provides a socket (2×4) for stacking the ESP01 on top of it, making it easy to power up and control high-voltage and high-current devices like lights, motors, or any dry-contact appliances.
This module is particularly useful for smart home IoT development, enabling you to control the relay via Android or iPhone apps and even connect it to various cloud servers for remote control and automation. It simplifies the integration of ESP8266-based IoT devices into your projects.
