Software Documentation: Air Mass Flow Sensor¶
This project contains the software for a student experiment at ETH Zürich based on sponsorship by Sensirion AG. The student experiment aims to illustrate the sensor principle of a thermal air mass flow meter, which is investigated mainly from the control point of view. The students are required to implement control algorithms for the regulation of the heater.
The software provided here mainly does two things:
Communication with all attached devices:
Sensirion SHT temperature sensors connected to a Sensirion Sensor Bridge
A Sensirion SFM massflow meter
A custom built heater being driven with a PWM signal
Displaying the current system status
Walking the student through different steps of the experimentation
Handling interactions with the setup
These tasks are solved with a PyQt5 based graphical user interface as described in section GUI.
