Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and provide an instant audible alert to them. So they can navigate independently. The best part of this blind ...

The DIN Rail IoT controller also features a 1.14-inch color display, a RESET/BOOT button, 3 user buttons, and a buzzer or user interaction. The M5Stack StamPLC also integrates an LM75 temperature ...

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 ...

Abstract: The paper proposes an S-shaped fiber Surface Plasmon Resonance (SPR) sensor structure capable of simultaneously measuring refractive index (RI) and temperature for the first time. The ...

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 ...

As for data, it’s hooked up with a GPS module and a BME280 environmental sensor for location. The balloon can figure out where it is, and tell you the temperature, pressure, and humidity up ther ...
