Humidity sensors

A simple display may be enough for a room you visit every day. Logged readings and an optional internet gateway serve a different need when trends or off-site alerts matter.

Decide whether you need a reading or a history.

Local display versus logged history
Bluetooth range versus remote gateway
Conditional accuracy and placement
Ambient RH versus material moisture
Alerts and replaceable batteries
