The SC22 Humidity Sensor is our outdoor version of the SC12. The SC22 has the same humidity and temperature accuracy as the SC12, but has additional sealing to enable outdoor use in a covered environment.

The sensor is ideal for monitoring occupant comfort and HVAC performance in buildings, server rooms, greenhouses, museums and other facilities where temperature and humidity are important. Remote email or text(SMS) alarms can also be enabled with our HaloCloud service.
