RM-1-ESP12, ESP12F + One Channel Relay Module for IOT(ESP8266)

ESP12F + One Channel Relay Module for IOT (ESP8266)

This is a One channel WiFi module equipped with an ESP-12F WiFi module (8 bit MCU). This MCU is capable of controlling relay at any time with some simple coding. By using a WiFi relay phone application, the user could control the relays from anywhere in the world as long there is Internet connectivity! 

Features:

• Onboard high-quality MCU and ESP-12F WIFI module
• Two working modes:

             Mode 1: cellphone carry on wifi module directly
             Mode 2: cellphone and wifi module carry on router together

• Additional function: ESP-12 works as a microcontroller when disconnected from the relay module
• Transmission distance:
  (1) In 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
•  Use the Smartconfig technology to complete the configuration of the account and password of the esp-12F WIFI module on the mobile APP. The configured account and password will be memorized after power off
• Power:
  Logic: 5V, Relays: 10A/250VAC OR 10A/30VDC, Cycles:100,000 times - protection diode for short and fast response time.
