Review: Item highly recommended I brought this item for my friend as he wanted something that he could control the temp and the humidity of a enclosure for his pet snake, so I built this that controls the heating Matt and the water level so it stays constant
Review: Eccellenti sensori. Utili per trasformare un SONOFF Basic in un regolatore di temperatura/umidità utilizzando il firmware Tasmota.

These work great. Only 3 wire saves a conductor. Easy to use, nice that they come with short cables to use during development. Arduino library makes interfacing easy.
