CM2302 Temp and humidity sensor

GrantmcF

I am looking to update one of my projects. I want to switch from an SHT11 to the CM2302 sensor. Are there any code objects already out there for the CM2302? I looked on the OBEX and did not find anything. I am still using the propeller tool V1.3.2 for my IDE.

I would bet that this device could be accessed with 1or 2 lines of Tycon Forth.

If you download BlocklyProp and run the code from this page:

You can view the C code created.

This is the same as a DHT22 and the code for this is built into Tachyon. However the obex does have code for the DHT11 and DHT22 as there is just a little timing difference between them.
