The inside of the rain sensor 8 is also provided with a piezoelectric sensor, which is specifically arranged on the rain cover 801. lower end. The principle is that the rain sensor detects the volume and distribution density of raindrops, and the volume of raindrops is proportional to the voltage generated by piezoelectric ceramics. Therefore, each raindrop signal can be directly converted into cumulative rainfall, and the signals not produced by raindrops are filtered out by low-pass filter technique. By detecting each individual raindrop, rainfall amount and rainfall intensity can be calculated with high precision. There are multiple ultrasonic sensors 5, and they are arranged on the same horizontal plane and perpendicular to each other.

The ultrasonic sensor has 4 equally spaced ultrasonic transducers located on the same level to form a transducer array. Wind speed and direction are determined by measuring the time it takes for ultrasonic waves to travel from one transducer to another transducer in the same line. The wind sensor measures the transit time (both directions) along the 4 paths formed by the transducer array. This transit time depends on the wind speed along the ultrasonic path. If the wind speed is zero, the forward and reverse transfer times are the same. When the wind direction is in the same direction as the sound path, the upwind travel time will be longer and the downwind travel time will be shorter. the
