Temperature Controlled Fan Circuit Diagram. The complete circuit to build the temperature controlled fan using arduino and lm35 project is given below, we have used fritzing software for making most ...

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; ...

HCSR04-DistanceMeasurement: Demonstrates how to measure distance using the HC-SR04 distance sensor module with Arduino. Keypad-Example: Allows the use of a keypad module with Arduino. Programming ...

Hence, developing a data acquisition system capable of continuously monitoring temperature and pH levels in water bodies, facilitated through a PC and wireless connectivity, is essential. This work ...
