NASHVILLE, Tenn. (WSMV) - The online petition ‘Mandate Installation of Metal Detectors in All Schools’ has nearly 2,000 signatures as of Monday morning. The petition was created on change.org ...

The UNO is one of the most popular boards in Arduino family and a great choice for beginners. Ultrasonic Sensor: These are the sensor that use ultrasonic waves to detect objects or to measure the ...

The steam and grease from kitchen work can clog smoke detector sensors so they don't work as well. These locations are bad news for smoke detectors, even if it may seem like a good idea at the time.

Finally, I need an analog soil moisture sensor so that I can monitor the soil moisture, and based on that, I can switch on/off the water pump remotely through the Blynk app. The below block diagram ...

From overflowing air conditioners in summer to frozen, cracked valves in winter, I've seen my share of leak problems. The worst leaks always go unnoticed to cause serious problems like warping ...

This paper presents a comprehensive review of solid-state metal pH sensors, with an emphasis on the potential of metal nitrides to address the limitations of glass electrodes and metal oxides. Metal ...

Abstract: Flexible strain sensors based on liquid metal have great application potential in wearable devices, biomedicine and soft robots due to their huge deformability, low hysteresis and high ...

The main drawback to using magnets alone is that they don’t differentiate between metal components like more advanced digital detectors. Dimensions ‎7 x 3.4 x 2 in. With 13 sensors—each ...

MagAlpha sensor detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on the rotating shaft. Unlike most Arduino & Genuino boards, the MagAlpha ...

Arduino Library for automatic detection of Sensirion sensors on an I2C Bus. It allows for easy read-out of the data of Sensirion Sensors using an ESP32 board. This project was developed and tested on ...
