Humidity control circuit using D flip-flop and operational amplifier
Source: InternetPublisher:无人共我 Keywords: D flip-flop control circuit operational amplifier BSP Updated: 2021/08/20
It uses D flip-flop Az (CD4013 type) as the control circuit , operational amplifier
Ai (LM324 type) as the measurement comparison circuit, humidity resistor RS (MOS1 type) as the moisture detection element, and relay KA
to control the humidification equipment. When the humidity is lower than the set value, KA loses power and is released, and the humidification equipment is put back into operation.
In the figure, RPi is the humidity adjustment potentiometer (adjusting the humidity set value).
