The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

AHT10 Temperature & Humidity Sensor. ... I’m happy I got the AHT10 sensor module and Arduino Uno working together. I never expected it to work without problems! There are still some mysteries, I agree ...

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&#… ...

Made by Renesas, the single-channel, non-dispersive infra-red module is called RRH47000 and has automatic baseline calibration for measurement from 0 to 5,000ppm. Also in there are temperature and ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

Bosch has introduced a four-in-one mems sensor that measures air pressure, humidity and temperature, aa well as detecting volatile organic compounds, volatile sulfur compounds (indicating bacteria), ...

It’s a simple enough idea, and with an Arduino and a DHT11 temperature and humidity sensor, it was pretty easy to put together. The clothes dryer used for this experiment was a self-ventilating ...
