HiGrow Plant Sensor alternative parts for DHT22

This project contains an alternative case to fit with HiGrow Plant Sensors that have been upgraded from DHT11 to DHT22.

DHT22 allows more accurate measurements compared to DHT11, but has a slightly larger size. The PINs are compatible, it can be changed 1:1. For details and a comparison between DHT11 and DHT22 see here on Adafruit.

Note that you need to change the definition in the Arduino Code when using DHT22 as described on Github.
```
//#define DHTTYPE DHT11 // DHT 11
//#def
