-This program was used to test DHT22 modules before installation. The DHT22 modules were tested for functionality at room temperature, pre-sorted in this way, and then frozen in a bag of moist sand in the freezer and tested again. One module displayed incorrect temperature values ​​in frost conditions. The display of negative values ​​did not comply with the specifications.+This program was used to test DHT22 modules before installation.
