Detailed Description:
AM2301 is a digital temperature and humidity sensor module made using a capacitive humidity sensor, a high precision temperature sensor and an 8 bit microcontroller. Former name of this sensor was DHT21. This module provides extremely accurate outputs as it is digitally calibrated using the coefficients stored in the microcontroller. It has a wide operating voltage range, 3.3V ~ 5.2V makes its interface easy with a wide variety of devices. AM2301 sensor module can be easily interfaced with Arduino Boards, Raspberry Pi and other microcontroller units with its single bus interface.
