From Meh to WOW - Improving Thermostat Accuracy with Temperature Sensor Hacking

Learn how to improve the accuracy of unreliable thermostats through a practical electronics hacking project in this 11-minute tutorial. Discover the common issues causing temperature measurement deviations of 1-2°C in typical room thermostats through detailed teardown and analysis. Explore the internal temperature sensing mechanisms and identify the root causes of measurement inaccuracies. Follow along as the presenter develops a custom solution using the Würth Elektronik WSEN-TIDS temperature sensor, complete with PCB design and implementation. Gain hands-on experience with sensor integration, including access to C source code drivers for STM32, Zephyr OS, and Platform.IO environments. Test the effectiveness of the hardware modification through comparative measurements and see how this "tiny hack" transforms mediocre thermostat performance into reliable, precise temperature monitoring.
