RHT03 + Raspberry Pi

Well… the DHT22 it’s not a RHT03!! DAMN

To make a Sparkfun RHT03 work on a Raspberry Pi I’ve found 2 solutions:



 ~ $ git clone git://git.drogon.net/wiringPi
$ cd wiringPi/
~/wiringPi $ git pull origin
~/wiringPi $ ./build
~/wiringPi $ cd examples/
~/wiringPi/examples $ gcc rht03.c -o rht -lwiringPi -lwiringPiDev
~/wiringPi/examples $ sudo ./rht 11 #GPIO17
Temp:  20.8, RH:  57.8%
Temp:  20.8, RH:  59.1%
Temp:  20.7, RH:  59.1%


$ git clone git://github.com/technion/lol_dht22.git
$ cd lol_dht22/
~/lol_dht22 $ ./configure
~/lol_dht22 $ make
~/lol_dht22 $ sudo ./loldht

Data not good, skip
Humidity = 59.40 % Temperature = 21.20 *C

Next steps… try to improve results with a Logic Level Converter
