5 Unique Sensor Types

The ISAAC O3 Multi-Sensor contains 5 unique sensor types that you can use to monitor rooms.

Temperature

Detect ceiling, surface, and human height temperature.

humidity

Humidity

Detect ceiling and human height humidity.

walking

Motion

Detect if there is motion in the room.

Light

Detect light level intensity.

waveform

Sound

Detect occupancy using sound from two on-board microphones.

Occupancy Count New!

Occupant estimation uses onboard sensors and machine learning to estimate the number of people in a space.
