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.

Treasure hunting is a good game for family bond; Moreover, through it, you can teach your kids a lot of things, such as reading a map, types of metals, how a metal detector works and how to use it.

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 ...
