Is it too cold, hot, humid, or dry in your home? Do you have a hunch but not sure? Any of these extremes could have an effect on your health.

Knowing the humidity inside your home is helpful. Too humid, and mold can grow as well as release allergens in the air that can cause health problems. Too dry, and other issues like throat, nose, and eye irritation may result. 

Regardless of health, sometimes times it's just fun to know the humidity and temp values of your environment!

With the AHT20 Temperature and Humidity sensor, an ESP32-S2 Feather and Adafruit IO WipperSnapper, you can easily track the temperature and humidity of your home or other locations. The best part - there’s no coding or soldering required!

In this guide, you’ll connect an AHT20 Temperature and Humidity sensor to an ESP32-S2 Feather. Then, load the AdafruitIO WipperSnapper firmware onto the ESP32-S2 Feather to connect your device to Adafruit IO. You'll configure the AHT20 sensor from the WipperSnapper website to send data to Adafruit IO. 

Finally, you’ll create a handy dashboard to view the temperature and humidity data.

Prerequisite Guide:

WipperSnapper is an interface for Adafruit IO, Adafruit's incredibly easy-to-use IoT platform, designed to turn any WiFi-capable board into an IoT device without programming a single line of code.
