Single relay module
The Bluetooth proximity switch single relay module is developed based on the XY-MBO21F module. It has multiple types of voltage regulators on board, supports 5-12V DC input, supports Bluetooth automatic sensing, and the module's relay will automatically turn on after the mobile phone Bluetooth connection, and automatically turn off after the Bluetooth is disconnected, so as to achieve the purpose of switching the output voltage. It has the advantages of proximity automatic sensing, support for APP/applets/serial ports and other methods to configure parameters, low power consumption, and stable performance.
5 core functions
1. Support mobile phone proximity automatic sensing switch, no need for APP system Bluetooth direct connection
2. Support APP/applets/serial ports and other methods to configure parameters
3. Support AT commands to modify the switch lock signal value, switch lock mode and switch duration
4. Reserve UART interface, support sending and receiving AT commands
5. Low power consumption and stable performance
