When the WiFi module and the mobile phone are running on the router at the same time, the transmission distance depends on the signal strength of the router.
Onboard 12V, 10A // 250V AC 10A // 30V DC relay, which can be activated continuously for 100,000 times, with diode discharge protection, and short response time.
Use Smartcongig technology to complete the account and password configuration on the mobile phone APP ESP-01 WiFi module, and configure the user name and password memory function.
Single board mode selection and real-time working status indication.
Reserve UART debugging interface and STM8 SWIM program download interface.

The 12V Dual WiFi relay module uses ESP-01 as the WiFi module and is compatible with 8-bit MCU chips. With a simple configuration process, the wireless control of 2 relays can be realized through the mobile phone APP.
Onboard ESP-01 WiFi module and high-performance microprocessor STM8S103.
The module has 2 operating modes:
Method 1: The mobile phone is directly installed on the WiFi module.
Method 2: Equipped with a mobile phone and WiFi module on the router
Additional function: When ESP-01 is unplugged, it can also be used as a USB relay.
Transmission distance: In an open environment, when the mobile phone is installed on the WiFi module, the maximum stable transmission distance is 100M.
