Smart sensors are an important part of smart homes and various Internet of Things applications. Various types of sensor modules can collect temperature, humidity, light, sound, various gases, heating elements, and any measuring instruments in the application environment. The data is transmitted to the central database and intelligently analyzed and processed through the network, so as to obtain the result data we need. Since the sensor module is located at the nerve endings of the entire system, it has the characteristics of large usage, wide distribution, and complex environment. It involves a large number of engineering problems in practical applications, and the largest engineering amount is the problem of transmission lines and equipment power supply. At present, with the improvement of wireless communication technology, a large number of wireless communication links are used, especially in smart home systems, more and more wireless communication technologies are used to reduce the amount of engineering. However, the problem of taking power from the equipment still exists, that is, laying power lines for the equipment is still an essential project. In the smart home system, the engineering problems involved are one of the main obstacles affecting the application and promotion.

For such sensing devices, it is possible to use solar power generation as the working energy of the device, so that the sensor module can be completely wireless, so that wireless environment sensing devices can be configured at any desired location, greatly expanding the application of smart home range and reduce operating costs.
