DHT20 Temperature and Humidity

MATLAB + Arduino I2C DHT20 Temperature and Humidity sensor support

Support for the latest DHT sensor: the DHT20

The DHT20 sensor is an I2C sensor and must be connected to the I2C port of the Arduino

1. First, define your Arduino in your workspace:

a = arduino('C','Nano3','Libraries',{'I2C'});

2. Then, tell MATLAB that there is a DHT20 sensor attached to it.

dht20obj = dht20(a);

3. Once you've created your sensor object, you can ask it to take temperature and humidity readings, or both:

myTemperature = readTemperature(dht20obj);
myHumidity = readHumidity(dht20obj);
myDHTSensorData = readRawSensorData(dht20obj);
% can also call it using . annotation:
dht20obj.readHumidity;
dht20obj.readTemperature;
dht20obj.readSensorData;
