Wifi Relay Module Esp8266 Relay Module Esp8266 Wifi Relay

GA2085 5V ESP8266 ESP-01 2 Channel WiFi Relay Module 2-Channel For IOT Smart Home Phone APP Controller1. onboard high performance microprocessor STM8S103 and ESP-01 WiFi modules 2. Working Mode Mode 1: mobile phone is directly mounted on WiFi module Mode 2: mobile phones and WiFi modules are equipped on routers simultaneously Additional function: it can also be used as USB relay when ESP-01 is pulled out3.Transmission distance In an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi module. When the WiFi module and mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router. 4.Operating instructions Step 1: the 5V/1A power adapter, the positive and negative poles of the power are connected to IN+ and IN- of the module respectively. Step 2: Android mobile terminal installation APP Esp Touch--Dem ", for the first use of work mode 2 to ESP-01 module configuration WiFi account number and password. Step 3: Android mobile terminal to install APP "Easy TCP--20", TCP transmission tool, used to send relay control instructions. Click on "SWITCH", and then enter the 2 relay control instructions and names and contents (instruction form HEX) by the gray blocks in the interface. 5. The use of Smartcongig technology in the mobile phone on the APP ESP-01 WiFi module to complete the account and password configuration, configured username and password memory function6.onboard 5V, 10A//250V AC 10A//30V DC relay, which can be continuously pulled for 100 thousand times, has diode discharge protection, short response time7.

description is as followed:
(1) Lights off, in self-configuration or disconnected
(2) Lights flashes quickly for 0.5s, it is waiting for the connection from APP of telephone to configurate Wifi account and password for ESP-01 module
(3)Lights flashes slowly for 2s, the configuration is completed and it's waiting for the TCP connection from telephone.
(4) Lights on, TCP connection with telephone is completed2 Reserved Jumper capNormal use, plug into the bottom(RX connects with RX1 TX connects with TX1).
