Description

The 12V dual WiFi relay module uses ESP-01 as the WiFi module and is compatible with 8 bit MCU chips. Only a simple configuration process can realize the wireless control of the 2 way relay by using the mobile phone APP in the lan.

Features:
1>. Onboard high performance microprocessor STM8S103 and ESP-01 WiFi modules.
2>. The module has 2 operating modes of work:
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 out.
3>.Transmission distance:
In an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi module.
4>. 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.
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 function.
6>. 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.
7>. Board mode selection and real time working status indicator.
8>. Reserved UART debug interface and STM8 SWIM program download interface.
9>. Board size: 59*40mm.
