Abstract
A rainfall sensor with LED lamps comprises an upper shell and a base, wherein the upper shell is used for bearing raindrop impact, and the base is used for installation of the upper shell. The rainfall sensor with the LED lamps is characterized in that the upper shell can vertically ascend and descend on the base; the base is provided with the LED lamps and a control switch of the LED lamps; a variable resistance device is arranged between the upper shell and the base; the variable resistance device, a power source, the LED lamps and the control switch form a circuit; elastic parts are further arranged between the upper shell and the base. When rainfall or raindrops become larger, the raindrop impact on the upper shell is larger, and the upper shell compresses the elastic parts to descend; the larger the descending degree is, the smaller the resistance value of the variable resistance device is; current in the circuit becomes larger, and the LED lamps become brighter. On the contrary, when the rainfall or the raindrops are smaller, the raindrop impact on the upper shell is smaller, the elastic parts are released, the resistance value of the variable resistance device becomes larger, the current in the circuit becomes smaller, and the LED lamps become dimmer. Accordingly, the magnitude of rainfall can be judged according to the brightness of the LED lamps.
