ESP8266 Wi-Fi Based 4-Channel Relay Home Automation Module

ESP8266 Wi-Fi-Based 4-Channel Relay PCB Board for Home Automation Project. This Board Included the Esp8266 module, 4-Channel 5V Relays, 817 Opto-couplers, DC Jack and other components with through-hole LED for indication purposes. This 5V 4-Channel relay board is controlled directly by esp8266 over Wi-Fi. 

This ESP8266-based Relay Module is suitable for wirelessly controlling appliances via WiFi. It is a four-channel relay module that can control up to 240V AC and 28V DC with a load capacity of 7A in 240VAC and 10A in 28VDC. ESP8266 will manage everything, once programmed and powered making it suitable for internet of things (IoT) projects. 

ESP8266 is a serial Port WIFI Wireless Transceiver Module for Arduino which is a small WIFI transceiver that is the perfect solution for home Automation and IoT applications. It can be the replacement of your NRF24L01, it can talk to your WIFI router directly through the UART MCUs.
