Dew Sensor Circuit Simple and Low Cost
This simple and low cost dew sensor circuit is basically a switching type circuit made with the help of a popular dual op-amp IC LM358N which is configured here as a comparator. Under normal conditions, resistance of the dew sensor is low and thus the voltage at its non-inverting terminal is low compared to that at its inverting input terminal. The corresponding output of the comparator is accordingly low and thus nothing happens in the circuit.
This is a simple and low cost dew sensor circuit that can be used to switch off any gadget automatically in case of excessive humidity. Dew adversely affects the normal performance of sensitive electronic devices.
