A humidity/frequency-audio decoding humidity detection, automatic exhaust ventilation and frog chirping circuit
Source: InternetPublisher:清宁时光 Updated: 2017/05/27
The circuit is shown in the figure. It consists of a humidity sensor, a time base oscillator, an audio decoder, a thyristor controlled exhaust fan circuit, a frog sounding circuit and an AC step-down rectifier circuit. When the ambient humidity reaches the set humidity value, the audio decoder will output a signal to control the start of the fan for ventilation and dehumidification. At the same time, several frogs will sound to remind the user to pay attention. Latest Control Circuits Circuits
