ESP8266 ESP-01 5V 4-Channels WiFi Relay Module for Home Remote Control Switch

ESP8266 ESP-01 5V 4-Channels WiFi Relay Module for Home Remote Control Switch is 4 channel WIFI relay module carrying an ESP8266 WIFI module and mature 8 bit MCU, with a Professional switching power supply circuit.It could control the relay by Android phone APP within the local area network (LAN). It is easy to set up.

Features:

1. Integrated design.
2. APP remote control.
3. DC 5V work power supply.
4. Onboard high-quality MCU and ESP8266 WIFI module.
5. Support Two Work Mode:
6. Mode 1:cellphone carry on WIFI module directly.
7. Mode 2: Cellphone and WIFI modules carry on router together.
8. Additional features: USB Relay Module(Without ESP8266).
9. Transmission distance:
10. In the open environment, when the mobile phone is carrying on the WIFI module, the maximum transmission distance is 100 meters.
11. When the WIFI module and cell phone carrier on the router at the same time the signal transmission distance depends on the router signal.
