Introducing the 2-Channel ESP8266 WIFI Relay Module, a versatile and efficient device designed for easy remote control of electrical appliances or devices. This module is equipped with an ESP-01 WIFI module and an 8-bit high-performance MCU, making it simple to configure and control the relays using a cellphone APP within the local area network (LAN). Key features and characteristics of the module include: On-board N76E003/STM8S003 and ESP-01 WIFI module, providing reliable performance. Two operating modes: Mode 1: Directly connect cell phones to the WIFI module. Mode 2: Connect both cell phone and WIFI module to the same router. An additional function allows the module to act as a USB relay module when the ESP-01 is unplugged. Transmission distance: In open environments, the maximum transmission distance is 100m when the cell phone connects directly to the WIFI module. When both the WIFI module and cell phone are connected to the same router, the transmission distance depends on the router's signal intensity. Smartconfig technology of ESP8266 is utilized to easily configure the password for the ESP-01 module using an APP. On-board 5V, 10A / 250V AC 10A / 30V DC relay, capable of continuous operation up to 100,000 cycles. The module also features diode effusion protection and offers a short response time. Model selection and working position are indicated by LED indicators on the module for easy monitoring. The module includes a preserved UART debug interface and MCU program interface for advanced users. With this 2-Channel ESP8266 WIFI Relay Module, you can conveniently control electrical devices remotely and efficiently, making it a valuable addition to your IoT and home automation projects.
