The 5V dual WiFi relay module uses ESP-01 as the WiFi module and is compatible with 8 bit MCU chip. Only a simple configuration process can realize the wireless control of the 2 way relay by using the mobile phone APP .
1.Onboard ESP-01 WiFi modules and high performance microprocessor STM8S103 .
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.
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. Onboard 5V, 10A//250V AC 10A//30V DC relay, which can be continuously pulled for 100 thousand times, has diode discharge protection, short response time.
6 .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.
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.
