HiGrow Plant Sensor alternative parts for DHT22
thingiverse
This project includes a replacement enclosure to match with the upgraded HiGrow Plant Sensors that have been modified from DHT11 to DHT22. DHT22 offers more precise readings compared to DHT11, but it has a slightly larger size. The pin connections are compatible and can be swapped 1:1. For further details and a comparison between DHT11 and DHT22, visit the Adafruit website. Note that you need to modify the definition in the Arduino Code when using DHT22 as described on the Github repository. ```c #define DHTTYPE DHT22 // (AM2302), AM2321 ``` We based our project on the HiGrow Rev1 case: thing 2791829 This project includes: * an alternative front enclosure * an alternative back enclosure for battery cover with clip-in feature * an alternative battery cover with clip-in feature * a clip-in cover for the DHT22 sensor * a spacer for DHT22 to prevent it from being pushed against the PCB button Thanks to * HiGrow and Luca Fabbri for their original case design and great work * Stefan Schultheis for his support in software, hardware, and project management
