Support mobile phone proximity automatic sensing switch, no need for APP system Bluetooth direct connection <br />2. Support multiple ways to configure parameters such as APP/mini program/serial port <br />3. Support AT command to modify switch lock signal value, switch lock mode and switch duration <br />4. Reserve UART interface to support sending and receiving AT commands <br />5. Low power consumption and stable performance <br />6. Sensorless link firmware MB021F (HID) low-power module</p> <p>Product Introduction: <br />The Bluetooth proximity switch single channel relay module is developed based on the XY-MBO21F module. It is equipped with multiple types of voltage regulators, supports 5V-30V DC input, and supports 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 turning off the output voltage. It has the advantages of close automatic sensing, support for APP/mini program, serial port and other ways to configure parameters, low power consumption, and stable performance.</p> <p>Parameter: <br />Power supply port: DC5-30V <br />Product size: 20 * 62mm <br />usage method: <br />1. Power the Bluetooth proximity switch single relay module (DC 5-30V power supply) <br />2. Turn on 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 <br />3. Turn off Bluetooth and the relay will disconnect; Turn on Bluetooth, the relay will turn on <br />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 "XY-MBO21F_HID Specification Book.PDF" in the attachment</p> <p>Package include: <br />Relay module X1 <br />4P single row needle X1<br /></p></div></div>
