NEW GUIDE: Adafruit HTS221 – Temperature & Humidity Sensor #AdafruitLearningSystem #Adafruit @Adafruit

A new guide in the Adafruit Learning System: Adafruit HTS221 – Temperature & Humidity Sensor

Humidity is the concentration of water vapor (water when it’s a gas) in the air and usually it isn’t something that you can see. Since you can’t see humidity, if you care about how much there is, you’ll have to measure it. This is where the HTS221 Temperature and Humidity Sensor by ST comes in. With a HTS221, you can take measurements of the relative humidity. which will tell you if environment you’re measuring is bone dry or sopping wet.

The HTS221 can measure relative humidity from 0%-100% rH,  and temperature from -40 to 120 degrees celsius, otherwise known as “really, really cold” to “way past boiling”. The humidity sensitivity is 0.004% rH, and the temperature measurements have a resolution of 0.016 °C thanks to its 16-bit ADC. Humidity is accurate to ± 3.5% rH between 20  and 80% rH and temperature is good to ± 0.5 °C between 15 and +40 °C.
