Sensing Humidity With The SHT15 + Arduino

The SHT15 is a digital humidity sensor that outputs a fully calibrated humidity reading. And… because what we are measuring is actually relative humidity, and relative humidity being relative to temperature, the SHT15 has a builtin digital thermometer. This makes things much easier to work with than sensors without a thermometer onboard. You can pick… Continue reading Sensing Humidity With The SHT15 + Arduino

Sensing Humidity With The HIH-4030 + Arduino

Humidity is weird. Even though we experience it all the time, it’s not something we can normally guess with any accuracy. This is probably because when we talk about humidity, we are talking about relative humidity. Relative humidity is relative to temperature, so a change in temperature alone is enough to change the relative humidity.… Continue reading Sensing Humidity With The HIH-4030 + Arduino
