The AM2301B is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the AM2302. In fact, this enclosed sensor looks an awful lot like the popular DHT22/AM2302 temperature and humidity sensors, but unlike classic DHT sensors, it has an I²C interface! This sensor has a typical accuracy of ±2% relative humidity, and ±0.3 °C at 20-80% RH and 20-60 °C. There is only one I2C address so it’s not a good option when you need multiple humidity sensors.
More about the AM2315C:
The AM2315C is a nice, enclosed temperature and humidity sensor from the same folks that brought us the AM2315. In fact, this enclosed sensor looks an awful lot like the popular AM2315 temperature and humidity sensors, but inside is the AHT20.
What is WipperSnapper?
With Adafruit.IO and WipperSnapper Firmware, you can effortlessly connect various components and sensors to any of the 20+ supported development boards to build an internet-connected electronics project. The best part is that you can configure and control these sensors from the web using Adafruit IO, all without the need for programming.

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.
