DHT22 - Humidity and Temperature sensor


DHT22 - Humidity and Temperature sensor

LabVIEW Version:

LabVIEW 2013 Student Edition


DHT22 is a sensor for humidity and temperature measurements.

DHT22 uses digital data on a single bus to transfer raw data from sensor.

Read the DHT22/AM2302 datasheet included in the code for more information and specifications.

Instructions on how to use Code:

The FPGA VI reads the data from sensor. RT VI read data from FPGA VI and convert it into humidity and temperature. Checksum confirms that data are not corrupted.

You can implement FPGA VI as SubVI or in different FPGA personalities.
