You can read temperature and humidity values with any software that connects to a serial port. Most conveniently you can use the [https://pypi.python.org/pypi/RuSocSci RuSocSci] library in python. Here is a little example how to write a script that reads the temperature and humidity and writes it to the standard output (console):

The temperaturehumidity device identifies as a buttonbox. Lab computer are set up in a way that makes the second buttonbox behave different from all other devices. If you are using both the buttonbox and the temperaturehumidity device, please look up the port name of the temperaturehumidity device in the windows device manager and if it is for instance 'COM3' then change the code above into:
<syntaxhighlight lang="python">
import temperaturehumidity
#!/usr/bin/env python3
th = temperaturehumidity.TemperatureHumidity()
import temperaturehumidity
print(th.waitString())
th = temperaturehumidity.TemperatureHumidity(port='COM3')
</code>
print(th.waitString())
