Temp Hum Press Sensorr not reading.

I have the following sensor (https://www.dexterindustries.com/shop/temperature-humidity-pressure-sensor/) and I have been using the following code (https://github.com/DexterInd/GrovePi/blob/master/Software/CSharp/GrovePi/Sensors/DHTTemperatureAndHumiditySensor%20.cs) to read in from digital port 4.

I use the following code:

IDHTTemperatureAndHumiditySensor sensor = DeviceFactory.Build.DHTTemperatureAndHumiditySensor(Pin.DigitalPin4, DHTModel.Dht22);;

sensor.Measure();

double sensorTempC = sensor.TemperatureInCelsius;
double sensorTempF = sensor.TemperatureInFahrenheit;
double sensorhum = sensor.Humidity;

Is that the right code to use? I am getting NaN for all the values even if I use other ports.

I am trying to implement this for a client and at a stopping point.

Thanks in advance!!

Start by reviewing the linked Software/CSharp/GrovePi/Sensors/DHTTemperatureAndHumiditySensor.cs implementation and the DHT22 usage shown in the issue. Check how DigitalPin4 and other ports are handled, then reproduce the NaN readings; done means determining whether the implementation supports this sensor and documenting or correcting the cause.
