DC 12V ESP8266 ESP-01 4- Relay Module WiFi Module for IoT Smart Home Mobile Phone APP Controller WiFi Relay

When the WiFi module and the mobile phone are running on the router at the same time, the nsmiion 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 discharge protection, and short response time.Use Smartcongig technology to complete the account and paword configuration on the mobile phone APP ESP-01 WiFi module, and configure the user name and paword memory function.Single board mode selection and real-time working status indication.Reserve UART debuing 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 proce, the wirele control of 2 relays can be realized through the mobile phone APP.Onboard ESP-01 WiFi module and high-performance microproceor STM83.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 routerAdditional function: When ESP-01 is unplued, it can also be used as a USB relay.nsmiion distance: In an open environment, when the mobile phone is installed on the WiFi module, the maximum stable nsmiion distance is 100M.The color of some components of the product may change, but the effect remains the sameColour: blueMaterial: metalPackage Contents:1 x ESP8266 12V WiFi RelayOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
