Description:12V dual WiFi relay module uses ESP-01 as WiFi module and is compatible with 8 bit MCU chips. Only a simple setup process can realize 2 way wireless control of the relay by using the mobile phone app on the phone in the lan. Feature:1gt;. Built-in high-performance microprocessor STM8S103 and ESP-01 WiFi2gt; modules. The module has 2 working modes:Mode 1: the mobile phone is directly mounted on the WiFi module.Mode 2: mobile phones and WiFi modules are equipped with routers at the same timeAdditional function: it can also be used as a USB transmitter after pulling out the ESP-01.3gt;. Transmission Distance: In an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi module.4gt;. When the WiFi module and the mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router.5gt;. Using the Smartcongig technology on your mobile phone in the ESP-01 WiFi module to complete the account and password setup, configured username and password memory function.6gt;. Built-in 12V, 10A//250V AC 10A//30V DC relay, which can be pulled continuously 100 thousand times, has diode discharge protection, short response time. Board mode selection and real-time working status indicator.8gt;. Reserved UART Debugging Interface and STM8 Swimming Program Download InterfaceUser Manual:Please prepare the following tools before use:12V/1A power adapter and "ESP Touch-Demo" APPstep1: 12V/1A power adapter, the positive and negative power poles are respectively connected to the IN+ and IN-module.Step 2: Android terminal mobile APP installation "Esp Touch-Dem", for the first use of working mode 2 to ESP-01 module configuration WiFi account number and password. Step 3: Android mobile terminal to install the "Easy TCP-20" application, a TCP transmission tool, used to send relay control instructions. Click "switch" and then enter the 2 relay control instructions and the names and contents (HEX instruction form) through the gray blocks in the interface. Operating instructions for two operating modes and additional function:Operating mode 1 (mobile phone mounted on ESP-01 module) instructions::1gt;. Plug in the ESP-01 module, the module turns on. About 4 seconds later, the green light changed from extinction to 2 seconds flashing. Configuration description.2gt;. AP hotspot signal sent by a mobile phone connected to the ESP-01.3gt; module. It opens the "Easy TCP-20" app and clicks "CONNECT". When the connection is successful, the green light flashes slowly from 2 seconds to normal. Click on the gray box to send instructions to control the relay switch. Working Mode 2 (Mobile phones and WiFi modules are equipped with routers at the same time) Instructions:1gt;. Connect the ESP-01 module, module power, light green light to slow flashing, and then press the S1 button to enter mode 2. Blue light, about 1 minute later to 0.5S flash, indicating waiting for "Esp Touch-Demo" "APP" for his WiFi configuration account and password.2gt;. At the moment, the phone line connected to the router. Open the "Esp Touch- Demo" "APP", enter the router password, click "confirm".3gt;. It expects the configuration to be successful when the APP interface shows the ESP-01 IP address (e.g. 192.168.0.189), indicating that the ESP-01 module has been successfully connected to the router, and automatically remembers the account number and password. The next input mode 2 will automatically connect (about 20-60 seconds to connect). It is important to note that the IP address 192.168.0.189 is dynamically assigned to the ESP-01 module by the router. The address may change the next time you reconnect. You can see the real-time IP address of the ESP-01 module in the router's device list.4gt;. Open the "Easy TCP-20" app and click "CONNECT". When the connection is successful, the green light flashes from 2 seconds to normal. Click on the gray box to send instructions to control the relay switch. Warm Tips:1gt;. For the first time using the WIFI configuration, the password time will be a little longer (about 1 minute). After the next boot is complete, the setup requires only 20 seconds, it can be automatically connected.2gt;. If you want to replace the router, power outages may restart or press the S2 key (press the S2 key to delete the previous WIFI storage account and password). In mode 2 to set up ESP-01 WiFi account and password.3gt;. The router signal when the ESP-01 memory is weak or does not lead to the connection being interrupted in the service area, the green light will turn off and try automatically. The key in this process to the abnormal state. When the green light for 2 seconds and slowly restore the connection that has flashing.4gt;. Mode 1 and mode 2 only when the green light for 2 seconds and slowly flashing or stable button can be used for the rest of the layout, self-configuration or wait for the setup process. The key is invalid.5gt;. ESP-0
