and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data

Check the datasheet for further details. Overview⇠ This module interfaces with the DHT22 (also DHT21, DHT22, DHT33, DHT44, RHT01, RHT02, RHT03, RHT04, RHT05, AM2301, AM2302, AM2303 and HM2301), an inexpensive temperature and relative humidity sensor similar to the DHT11, but wi...
Datasheet PDF Parts with Similar Specs Overview of the DHT11 TheDHT11is a commonly used temperature and humidity sensor that comes with a dedicated NTC to measure temperature and an8-bit microcontrollerto output the values of temperature and humidity as serial data. The component is a 4-pin ...
This will make the data appear correctly for the correct sensor. Upload the sketch! You should see the temperature and humidity. You can see changes by breathing onto the sensor (like you would to fog up a window) which should increase the humidity. You can add as many DHT sensors as yo...

One other thing; the DHT22 moves along at a fairly peppy clip, so the PIC needs to keep pace. Run the microcontroller on a 20 MHz resonator so it doesn’t fall behind. On the other hand, the sensor can only update itself every two seconds, so don’t query it more often than that...
