Research direction

Start with the dht library entry point and reproduce the DHT22 reading in subzero temperatures, checking the reported -3264.4°C value. Compare the behavior with the linked Raspberry Pi forum discussion; done means the library reports valid negative temperatures or clearly documents the limitation.
