It’s getting hot in here.

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 ...

Tired of condensation wrecking your shed tools or greenhouse gear? I built a no-frills ESP32 + DHT22 node that wakes every 15 minutes, grabs temp/humidity data, beams it over Wi-Fi, and sleeps—running ...

Some sensors output a processed analog signal that is linear with respect to the physical quantity being measured. Some perform quantization as well and provide a digital output. Though it is easy to ...

Spring showers may bring flowers and sunlit afternoons, but they also bring moisture that creeps into walls, ceilings and ...

The wearable sensor market is growing at an annual compound rate of 17.8%. However, sensors have challenges, particularly in terms of miniaturization and power consumption. Several key parameters are ...

When it comes to testing microelectromechanical system devices and sensors, sometimes you have to shake and bake. and sensors are physically different from standard ICs. They require a specific type ...
