DIY dew heater controller
Hi all,
I decided to make myself a 3 channel dew heater controller. It features 3 PWM controllers with thermistors so as the temperature drops, the power to the dew heaters increases. The thermistors are mounted in a compartment at one end that has a fan blowing on them. Not quite as good as humidity sensors but still responsive to the air. I’ve used RCA plugs so that it conforms with industry standard heater straps too. Also features an LCD screen to set the wattage of each heater. Sadly I couldn’t find one with red backlight but at least I can turn the backlight off once set. All in all I’m pretty happy with how it came up.
Cheers
Ryan
