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!
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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
