ESP8266 ESP-01S Relay module Relay WIFI smart socket for Arduino

This WiFi relay based on AI-Thinker ESP-01/ 01S WiFi module, we use the GPIO0 of ESP-01/ 01S to control the relay by low level. It’s easy to DIY your smart switch to any device by your phone anywhere with this smart relay.
support the APP and LUA source code, it can be used for smart home, IOT and other DIY projects.

Product size: 37 * 25mm
Operating voltage: DC5V
Working voltage: DC 5V-12V
Communication: WIFI (ESP8266 module)
Transmission distance: the maximum transmission distance of 400m (open environment, mobile phone equipped with WIFI module)
Load: 10A/250VAC 10A/30VDC, the relay pull 100,000 times

Warnings:
This module requires a 3.3 volt supply for VCC, and 3.3V logic. It is not 5V tolant. Connect RX or TX on 5V Arduino will
destroy this module. You must use a logic level converter, or a 3.3V Arduino
The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module. You must provide a separate,
higher 3.3V supply(about 300mA or better)
The ESP8225 module is very new on the market and support and documentation for it is currently very limited.
