ESP8266 WiFi 4 Relay Module (5V)

Regular price LE 280.00

Introduction :

ESP8266 WIFI 4-Channel Relay Module is 4 channel WIFI relay module carried a ESP8266 WIFI module and mature 8 bit MCU, with Professional switching power supply circuit.It could control the relay by Android phone APP within the local area network

Transmission distance

1) the open environment, the mobile phone when carrying on the WIFI module maximum transmission distance of 100 m;
(2), when the WiFI module and cell phone carrying on the router at the same time the signal transmission distance depends on router signal


Features :

  • Integrated design.
  •  APP remote control.
  • DC 12V work power supply.
  •  Onboard high-quality MCU and ESP8266 WIFI module.
  •  Support Two Work Mode:
  •  Mode 1:cellphone carry on WIFI module directly.
  •  Mode 2: cellphone and WIFI module carry on router together.
  • Additional features: USB Relay Module(Without ESP8266).
  •  Transmission distance:
  •   In the open environment, when the mobile phone is carrying on the WIFI module, the maximum transmission distance is 100 meter.
  •   When the WIFI module and cell phone carrying on the router at the same time the signal transmission distance depends on the router signal.
