The Aqara FP300 is a battery-powered presence sensor with Thread and mmWave radar, giving HomeKit precise motion and ...

This approach eliminates costly metals, toxic chemicals and specialised fabrication infrastructure — opening the door to ...

This humidity sensor consists of 2 copper conductors that are located at small distance from each other. The relay switches as soon as the moisture makes a connection that is more or less electrically ...

If you want to measure humidity (and temperature, and maybe even barometric pressure) in a device that you’re building, have a look at this comprehensive test of seven different options. We’re going ...

Relative humidity, or RH, is the percentage of moisture in the air referenced to the maximum level of moisture the air can hold at that temperature and pressure. Early humidity sensors used natural ...

Würth Elektronik has shrunk a humidity sensor into a 1.5 x 1.5 x 0.5mm 5pad DFN package. Called 2525020210002, it works over 0 – 100% relative humidity, typically to within ±1.8%RH (±3.5%RHmax) over ...

Temperature and humidity sensors are advanced devices that give us real-time and accurate updates about both the temperature and humidity of the environment. It’s an efficient way for homeowners to ...

As discussed in the first part of the article, the accuracy with which sensor capacitance can be measured using absolute capacitance measurement has a significant dependency on the accuracy of the ...
