ESP8266 ESP-01 12V 4, Channels WiFi Relay, Module Things Smart, Home Remote Control, Switch

The Things Smart Home Remote Control Switch ESP8266 ESP-01 12V 4 Channels WiFi Relay Module is a WiFi relay module that includes a microprocessor and an ESP8266 WiFi module. The mobile phone application and implementation within the local area network (LAN) for wireless control relay will receive the serial port instructions from it.

This module is perfect for using WiFi to manage higher voltages in your project. With the help of this 4-channel relay module, 30V DC and up to 250V AC can be turned on. This enables you to incorporate features like as controlling devices, turning on remote lights, or setting off systems upon receiving a signal from an ESP8266 module.

An LED on the module illuminates based on its current condition. An LED that turns red to activate power is activated when a signal is received on the IN pin. A loud click indicates that the relay has detected a signal and has connected the output pins. The ESP8266 that is included is used to control the relay. For this to operate fully, UART setup is required. It is perfect for use in internet of things (or “IOT”) based projects since, once programmed and powered, it will take care of itself.

How to Use:

1. 12V/1A power adapter and APP “ESP Touch–Demo”
2. Step 1: The 12V/1A power adapter, the positive and negative poles of the power are connected to IN+ and IN- of the module respectively.
3. Step 2: Android mobile terminal installation APP”Esp Touch–Demo”, for the first use of work mode 2 to ESP-01 module configuration WiFi account number and password.
4. 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.

Features:

1. Transmission distance: In an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi module.
2. 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.
3. The use of Smart config technology in the mobile phone on the APP ESP-01 WiFi module to complete the account and password configuration, configured username, and password memory function.
4. Onboard 12V, 10A//250V AC 10A//30V DC relay, which can be continuously pulled for 100 thousand times, has diode discharge protection, short response time.
5. Board mode selection and real-time working status indicator.
6. Reserved UART debug interface and STM8 SWIM program download interface.
