AM2301 Temperature & Humidity Sensor Industrial

AM2301 Temperature & Humidity Sensor Industrial Price in Pakistan

The AM2301 or also known as DHT21 digital temperature sensor is one of the common from the range of DHT Temperature & Humidity sensors and boasts a relatively high temperature measurement accuracy of ±0.3℃ better compared to the DHT11 or DHT22 and with a relative humidity accuracy of +/- 3%. It has only 3 wires, including power and ground, meaning only one digital pin is required to interface it to a microcontroller.

For Arduino development platforms the sensor is very well supported by the DHT library available from the Arduino Playground website.

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.
