Home smart lighting control and indoor environment monitoring system 

There are 3 lights in the room, all of which are traditional push switches. The switch position of the house is not very reasonable. Therefore, when sleeping at night, you need to get out of bed to turn off the lights, which is slightly inconvenient. Combined with the BLE communication capability of RSL10, this The work designs a small system that uses a mobile app to wirelessly control three switches and obtain the RSL10 beacon temperature.
If it is developed according to commercial standards, software engineers and structural engineers are required, which is obviously unrealistic. Therefore, this work achieves the expected function based on technical principles: the mobile app controls three indoor switches and reads the temperature through BLE. The working diagram of the three switches is as follows. COIN-GEVB is used to read the temperature.

This project uses RSL10 BLE communication technology to realize wireless control of the switch node; the mobile phone Bluetooth is used as the Central device, and the switch node is used as the server device for two-way communication.

Switch hardware module - the current household switches are basically mechanical single live wire control switches, and they are 220V mains power, which has a certain degree of danger; therefore, it was decided to use external machinery for control; the power supply of the steering gear drive board The power supply can be connected to external photovoltaic power generation equipment. Combined with the low power consumption characteristics of RSL10, it can realize self-circulation of household cleaning. The steering gear can achieve more precise angle control and can be used to control the opening and closing of mechanical switches. RSL10 comes with I2C peripherals, and uses I2C to control the PCA9685 to generate PWM to drive the servo; for the opening and closing of the mechanical switch, 2 angles can be set. The angle setting needs to be adjusted for each switch.
