【Training Camp】【Training Camp】EasyEDA-Induction Light-659344A

The sensor light will not light up when there is light during the day. It will light up when the light intensity drops to the evening or night and someone passes by the sensor light. The sensor light and the light intensity of the sensor light can also be turned on and off by a manual switch. There is also a switch to adjust the sensitivity of human body sensing. In the entire circuit, the high and low levels of the PWM output cannot be directly used to control the switch of the sensor light. A transistor must be connected to the output end of the PWM to amplify the current input to the sensor light to meet the power of the sensor light. Note that the transistor emitter must be connected to the corresponding resistor to achieve the power amplification effect. In the project, I forgot to connect the corresponding resistor to the transistor emitter, which resulted in the sensor light not being able to achieve the ideal switch effect at the beginning. The corresponding resistor needs to be added later to achieve the effect. In addition, there is the networking of WB3S. A WB3S module cannot be connected to the network no matter how it is connected, and even the device name is not displayed. Later, a new module was replaced to solve the problem. The module can be connected to WIFI or Bluetooth with a mobile phone Tuya Smart. The switch and brightness of the sensor light can be controlled through the Tuya Smart software, and some networking functions such as whether someone has passed by can also be tested.
