Description ESP8266 ESP-01 / ESP-01S Relay WiFi Smart Control Module for Arduino

The ESP8266 ESP-01/ESP-01S WiFi Relay Module is an innovative solution for remote control of devices. This compact module uses the reliable AI-Thinker ESP-01/01S WiFi module. Through the GPIO0 port, it sends signals to activate a relay at a low level. This makes it easy to make any switch smart. So you can control devices from anywhere with your smartphone. It supports both APP and LUA source code. This makes it a perfect choice for smart home systems, Internet of Things (IoT) projects and other DIY creations. With a working voltage of DC 5V-12V and a working current of at least 250mA, this module is designed for versatility and reliability. The maximum transmission distance of 400 meters (in an open environment) increases the flexibility of placement and use.
