Temperature & Humidity Sensor Wiring & Example Code

The CM2302 Temperature and Humidity Sensor can take a reading of temperature and relative humidity for use by a microcontroller such as the Propeller.

Schematic and Wiring

       Schematic for wiring the 28059 Temperature and Humidity Sensor.    

Quick Code Example

The example code below displays the temperature and relative humidity in the BlocklyProp Terminal.  BlocklyProp uses integer math; the Temp & Humidity value block provides a value that is 10 times larger than the sensor reading. 

To display the sensor readings as floating-point values, use the Terminal print multiple block.  Click its gear icon, drag in text and floating point number blocks, and then click specify digits box:

Here is the complete code listing:

Save and run the project to display the data in the BlocklyProp Terminal:
