As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...

The researchers have used their own patented nanotechnology to build one of the fastest humidity sensors in the world. Although not yet available commercially, the device may be used one day in ...

If you want to add humidity and temperature sensors to your home automation sensor, you can — like [Maker’s Fun Duck] did — buy some generic ones for about a buck. For a dollar, you get a ...

An Environmental Monitoring Sensor Node, including a barometer, thermometer, light intensity, resistive rain, ultra-violet (UV) index, humidity, motion, and noise sensors, is included in the ...

Using an Arduino, a moisture sensor, an LED matrix, and a few other parts, dr.mcc's build monitors the moisture level in a pot of soil and then lets you know when the plant needs water by ...

Have the new HomePod 2 or HomePod mini smart speakers? If so, you’ve got access to built-in temp and humidity sensors with software 16.3 which can be useful in a variety of ways. Here’s how to ...

The sensors proved reliable and sensitive to changes in temperature and humidity levels. They successfully detected changes in relative humidity levels from 20% to 90% and temperature variations ...
