In this paper, we propose a fiber-tip laminar flow rate sensor with temperature compensated based on three-beam interferometer, which is composed by a piece of polydimethylsiloxane (PDMS) and air in a ...

This project uses Arduino, an LM35 temperature sensor, a buzzer, and an HC-06 Bluetooth module to measure ambient temperature, trigger an alarm when the temperature exceeds a certain threshold, and ...
