The AM2315C is an enclosed I2C temperature and humidity sensor featuring the modern AHT20 sensor inside a rugged housing with mounting bracket. It offers the same convenient form factor as the original AM2315 but with an updated sensor that supports a wider 2.5V to 5.5V supply range, making it compatible with both 3.3V and 5V microcontrollers.

With built-in pull-up resistors and standard I2C communication, this sensor connects easily to any Arduino or Raspberry Pi. The enclosed design provides much better environmental protection than bare PCB-mounted sensors, handling wind, rain, and outdoor conditions with ease. Take readings as frequently as you like — no timing-critical protocol to worry about.
