With the mature and stable 8-bit MCU chip, only a simple configuration process can realize the wireless control of the relay in the local area network using the mobile phone APP Parameter: Onboard processor: STM8S103 and ESP-01WIFI module Operating mode: Mode 1: The mobile phone is directly mounted on the WIFI module; Mode 2: The mobile phone and WIFI module are loaded on the router at the same time; Additional function: It can also be used as a USB relay when ESP-01 is unplugged. Transmission Distance: (1) In an open environment, when the mobile phone is mounted on the win module, the maximum stable transmission distance is 100m; (2) When the WIFI module and mobile phone are installed on the router at the same time, the transmission distance depends on the signal strength of the router. Function: Use Smartconfig technology to complete ESP-01 on mobile phone APP WIFI module account password configuration, the configured account and password have power-off memory function; Onboard: 10A / 250V AC 10A / 30V DC relay, which can be connected 100,000 times continuously, With two-pole effusion protection, short response time; on-board mode selection and real-time working status indicator. Reserved: UART debugging interface and STM8 SWIM program download interface Suitable for mobile phones: Android phones, not for Apple phones IN +, IN-: 5V / 12V power input; TX, RX: UART serial port pins; 5V / 12V, GND, SWIM, NRST: STM8S microcontroller program download port Button S1: mode switch, the default is mode 1 Button S2: Restore factory settings LED D2 and D4 (red light): relay working indicator, light when open LED D7 (red light): Mode 1 indicator LED D5 (blue light): Mode 2 indicator LED D6 (green light): working status indicator, described as follows: (1) When off, it means that it is self-configuring or loses connection with the router; (2) When flashing at 0.5S, it means waiting for the APP to configure a WIFI account for the ESP-01 module And password; (3) When the 2S flashes slowly, it means the configuration is completed, waiting for the establishment of a TCP connection with the mobile phone; (4) Steady light indicates successful establishment of TCP connection with mobile phone. Two reserved jumper caps: please plug them into the bottom end (that is, RX connected to RX1, TX connected to TX1) during normal use, if you want to use the USB to TTL serial port module to debug the ESP-01 module, please insert it to the top ( Otherwise there may be interference). COM1: public terminal; NC1: normally closed end, the relay is short-circuited with COM1 before pull-in, and hangs up after pull-in N01: Normally open, the relay hangs before closing, and shorted to COM1 after closing. COM2: public terminal; NC2: Normally closed end, the relay is short-circuited with COM2 before pull-in, and hangs up after pull-in; N02: Normally open, the relay hangs before closing, and shorted to COM2 after closing.
