The "Temperature Sensors" course of the Sensors and IoT course path, presents and analyzes various temperature sensors and how to equip wheeled robots with them, especially thermistors, in order to make the robots capable of detecting the temperature of different target objects and complete tasks in indoor environments. Firstly, students are introduced to the basics of temperature detection with thermocouples and other devices. Then, students study the structure of thermistors and learn how to mount them on the wheeled robot created in the wheeled robot course series. Afterwards, the basic mehthodologies for processing the analog signal of the temperature sensor and for converting it to a digital signal through an Analog-to-Digital Converter (ADC) are analyzed and the Python programming functions for getting the temperature reading is presented. Finally, students are challenged to complete the temperature detection of a room object task with the Raspberry Pi-based wheeled robot and by utilizing all the skills they have attained.
