AOSONG AM2315 I2C Temperature / Humidity Sensor

This robust AM2315 temperature and humidity sensor is suitable for outdoor use. The measured data is transferred to the microcontroller via the I2C bus. Two 10 kOhm pull-up resistors to VDD are required for operation on an Arduino. If other sensors with pull-up resistors are already connected to the I2C bus, they can be omitted. The sensor can be mounted with the supplied brackets.

Recommended alternative for outdoor use: SHT31 Weatherproof Temperature and Humidity Sensor
