Passive IR (PIR) sensors are excellent devices for wireless sensor networks (WSN), being low-cost, low-power, and presenting a small form factor. PIR sensors are widely used as a simple, but reliable, ...

The DS18B20 library supports only the DS18B20, only one sensor per pin, no parasite mode, no Fahrenheit and no alarm functions. The only feature the class supports is the asynchronous reading of the ...

The kit has parts and sensors to help beginners learn how to connect things, write code, and make projects without any ...

<p>Modern smartphones use proximity sensors for much more than just turning off screens during calls. These advanced sensors, powered by IR emitters and receivers, detect nearby objects like ...

In this paper, a novel Sagnac Interferometer (SI) based chalcogenide Photonic Crystal Fiber (PCF) temperature sensor is theoretically and numerically analyzed operating in the mid infrared (MIR) ...
