Hello members ;
I'm planning to modify the humidifier shown in the photo so that I can increase or decrease it's rate of humidification using a voltage ramp up or ramp down respectively ; instead of it's 10k rheostat being used. I know in one approach is to use a digital potentiometer link to other auxiliary circuits. But i can't get a digipot in our local shops here in Kenya.
This humidifier also has a mechanism of shutting down (even if it's switched on) when it's vibrator is not covered with water. And I was thinking that it could be possible to link this this feature to some sort of auxiliary PWM circuits to control it's output. But i can't get it's electronic circuit diagram online.
Is there anyone here who can help me with it's circuits or a similar circuit ; or any other alternative approach for me to implement my idea....
