Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

If you think the AHT10 is your next sensor to experiment with, stay for a while! AHT10 Temperature & Humidity Sensor. The datasheet says the AHT10 is a digital temperature and humidity sensor embedded ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...
