Product details

CO₂, VOC Index, Temperature and Humidity

Sensirion sensors monitor CO₂, VOC Index, temperature and humidity.

CO₂
400–5000 ppmAccuracy: ±5%
VOC Index
0–500
Temperature
−10°C to 60°C (14°F to 140°F)Accuracy: ±0.1°C (±0.18°F)
Relative humidity
10–100% RHAccuracy: ±1.0% RH

Recommended operating conditions

Temperature
5–60°C (41–140°F)
Relative humidity
20–80% RH

Adapter power and reporting intervals

USB power supports continuous air-quality monitoring. Use the supplied THIRDREALITY adapter.

Reporting intervals can be set from 30 to 300 seconds through Home Assistant or the THIRDREALITY app.

Use readings in your own automations

Create automations and set thresholds in your compatible hub. For example, an automation could turn on a connected exhaust fan when CO₂ exceeds 1000 ppm, respond to a rise in VOC Index with a purifier, or use humidity to trigger a dehumidifier.

Setup and remote monitoring

Connect the sensor to the supplied power adapter, then pair it through your compatible app and Zigbee hub. After pairing, use the connected app to check readings remotely.

Compatible hubs and connection routes

Compatible options include Home Assistant (ZHA or Zigbee2MQTT), SmartThings (2015/2018), Aeotec, Hubitat, Homey Bridge, Homey Pro and THIRDREALITY Hub Gen2 Plus.

Direct Echo pairing requires a model with a built-in Zigbee hub. The listed models include Echo (4th Gen), Echo Plus (1st and 2nd Gen), Echo Studio, Echo Show 8 (3rd Gen), Echo Show 10 (2nd and 3rd Gen) and Echo Hub.

Apple Home and Google Home connect through Smart Bridge MZ1, sold separately.
