A temperature data-acquisition system for open-wheel series racecar drivers

Thermal stress is known to be a major factor in deteriorating the human performance. The aim of this work is to prototype a data-acquisition system that can accurately record real-time temperature measurements for racecar drivers. The system has to be compact and portable to be accepted by the racecar drivers and league officials. The proposed solution is mixed-signal data acquisition system that integrates a temperature-to-voltage conversion sensor with an analog signal conditioning circuit and a digital data storage component. The system is battery powered and the data points stored in the memory can be easily retrieved and displayed in a spreadsheet application. The results show that created system can store more than 2000 data points with a temperature resolution of around 0.016 °C.
