I'm wanting to build a remote switch to turn on/off my dehumidifier (or humidifier in winter) that is driven by a humidistat.
The humidistat opens/closes a switch based on the humidity level. I have a spare ceiling fan remote control (Harbor Breeze) that will work for the remote part. The problem I have is, I need to simulate the pressing of a button when the humidistat switch is closed, and then simulate the pressing of a button when the switch is open. With the fan remote, I can either use the same button (the one that powers on the light), or 2 different buttons (high fan speed, off). The light button will dim/brighten the light based on how long it is pressed, so I would be looking for a quick pulse if I use this button.
I have been told that I need to use a dual monostable circuit, aka “one-shot timer”. A coworker told me to get an Arduino controller, but I want to verify it will do what I need first.
Any suggestions ?
