Hardware Composition

  • E104 - BT08 BLE module: Serves as the main controller, responsible for receiving data from the light sensor and controlling the opening and closing of the curtains.

  • Light sensor: Used to detect the intensity of ambient light.

  • Electric curtain motor: Opens and closes the curtains based on the control signals from the E104 - BT08 BLE module.

Software Design

  • Light sensor data collection: Real - time collection of ambient light intensity data through the light sensor.

  • Data transmission: Transmit the collected light intensity data to the E104 - BT08 BLE module via the BLE protocol.

  • Control logic: The E104 - BT08 BLE module determines whether to control the opening and closing of the electric curtain motor based on the received light intensity data.

  • Curtain opening and closing control: According to the control logic, the E104 - BT08 BLE module sends control signals to the electric curtain motor to achieve automatic opening and closing of the curtains.

Implementation Steps

  • Hardware connection: Connect the light sensor to the E104 - BT08 BLE module, and then connect the E104 - BT08 BLE module to the electric curtain motor.

  • Configure the E104 - BT08 BLE module: Configure the operating mode and parameters of the E104 - BT08 BLE module via AT commands.

  • Write the control program: Develop a program to achieve data collection, transmission, and control logic for the light sensor.

  • Testing and debugging: Conduct system testing and debugging to ensure stable system operation.

By combining the E104 - BT08 BLE module with a light sensor, the light - linkage function for intelligent curtains can be realized. The E104 - BT08 BLE module, with its compact size, low power consumption, support for multiple operating modes, and rich interfaces, is an ideal choice for achieving this function.
