Example Circuit for DHT11 or 22

by LitlNiky on Fri Jun 14, 2013 8:59 am

I need to deliver two functions;

1) a Humidity switch that turns on (presents a closed contact or some kind of out put to drv either an optoiso or relay) for the condition of 5% or less?.

2) to provide a similar function for a specified temperature (aprox60C) that trips and latches with reset of course


thanks
Nico

Follow the circuit example here: http://learn.adafruit.com/dht/connectin ... txx-sensor
You don't specify what you are driving with the output, but the Powerswitch Tail is opto-isolated, can switch up to 15A @120v and can be driven directly from an Arduino output. http://www.adafruit.com/products/268
