Adafruit AM2315 - Encased I2C Temperature/Humidity Sensor

AM2315C is an advanced I2C-interface temperature and humidity sensor encased for durability and enhanced functionality. It combines a thermistor temperature sensor and a capacitive humidity sensor for accurate environmental readings.

This device stands out with its durable casing and mounting bracket, providing a significant advantage over traditional PCB-mounted sensors. While not officially weatherproof, its robust design performs well in environments exposed to elements like wind and rain.

Featuring an I2C interface, the sensor ensures straightforward integration with various microcomputers unable to handle the precise timing required by other sensors. The wiring is simple: connect the red wire to 5V power, black to ground, yellow to your I2C data pin, and white to the I2C clock pin.

Known to be compatible with Arduino, the sensor leverages an example library available on GitHub for executing temperature and humidity readings. Keep in mind the sensor supports only one instance per I2C bus due to its fixed address, and requires two 10Kohm pullup resistors for proper operation, which must be purchased separately.
