The Bluetooth proximity switch single relay module is developed based on the XY-MBO21F module, with multiple types of voltage regulators onboard. It supports 5V-35V DC input and Bluetooth automatic sensing. After connecting to the module via Bluetooth on a mobile phone, the relay will automatically turn on, and after disconnecting Bluetooth, it will automatically turn off, achieving the purpose of switching off the output voltage
It has the advantages of near automatic sensing, support for configuring parameters in multiple ways such as APP/mini program/serial port, low power consumption, and stable performance

Functional Features
Automatic sensing switch: Innovative proximity sensing technology enables mobile phones to automatically switch on and off when approaching, without the need for tedious operations, bringing a seamless intelligent experience
Multi platform configuration support: Whether through an app, mini program, or serial port, device parameters can be easily configured to meet the personalized needs of different users
Flexible AT command control: supports modifying switch lock signal values, modes, and durations through AT commands, providing a highly customizable operating experience
UART interface reservation: The device reserves a UART interface for developers to send and receive data through AT commands, expanding device functionality
Low power consumption and high performance: Optimized energy management ensures that devices can maintain stable performance output even in a low-power state
Instructions for use
1. Provide power to the Bluetooth proximity switch single relay module (DC 5-30V power supply)< br>
2. Open the Bluetooth system of your phone, search for Bluetooth devices and connect them (starting with NBH). The initial pairing password is 123456. Check the Bluetooth connection status of your phone, and the module's serial port will output connection information:
3. Turn off Bluetooth, the relay will disconnect; Turn on Bluetooth, the relay will turn on
4. For operations such as changing Bluetooth name and password, modifying relay switch lock signal value, switch lock mode and switch duration, please refer to the attached "XY-MBO21F_HID Specification Book.PDF"
