BMP180-PressureMeasurement: Demonstrates how to measure pressure, altitude, and temperature using the BMP180 sensor module with Arduino. HCSR04-DistanceMeasurement: Demonstrates how to measure ...

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.

The circuit reads the temperature from the LM35 sensor, displays the values in the serial monitor, and lights up the corresponding LED: Red LED: Temperature ≥ 30°C; Yellow LED: Temperature ≤ 20°C; ...

Temperature sensing technology has undergone significant advancements in recent years, leading to the development of modern temperature sensors with enhanced accuracy, reliability, and versatility.
