Measuring ambient temperature with an analog sensor
The upm library includes support for the Grove analog temperature sensor breakout board in the pyupm_grove module. The GroveTemp class declared in this module represents the analog temperature sensor connected to our board. The class makes it easy to retrieve the raw values read from the analog input into values expressed in degrees Celsius (ºC).
We will create a new TemperatureSensor class to represent the temperature sensor and make it easier for us to retrieve the ambient temperature values without worrying about unit conversions that are necessary when working with an instance of the GroveTemp class. We will use the GroveTemp class to interact with the analog temperature sensor. The following lines show the code for the new TemperatureSensor class that works with the upm library, specifically with the pyupm_grove module. The code file for the sample is iot_python_chapter_07_04.py.
