i am off to school but today when i get home one the things i need to work on is how to switch my humidity device on/off, i have the sensor part under control now its down to switching. Its a simple on for x time (few seconds normally sometimes more) then of for anything from couple seconds upto 30 mins or more depending on the readings,
the unit itself is one of those foggers you can get for reptiles and stuff.
Voltage is 24VAC, i was thinking triac but the opto's i have are not zero cross detect (does it matter?) or i have a Mosfet circuit in mind with a rectifier. going to have a think about it at school, and report back later. slowly getting it all together (too slowly tho) soon it will be code time other job for today is look at seven segment displays, my choice is a scanning technique or i might just use a shift register. i have multiplexed displays and some normal ones.
anyway back later!
