Use a temperature sensor to measure your skin temperature, and register the output with three LEDs. Even though the Arduino is a digital tool, it can interpret signals from an analog input, like the ...

This project is a simple temperature monitoring system using an Arduino UNO, a TMP36 temperature sensor, and an Op-Amp 741. The system lights up an LED when the temperature exceeds 30°C. 🛠️ Tools ...

This isn’t about connecting a temperature sensor in your Arduino. ... 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.
