Aranet CO2 and Temperature Sensor | 0-9999 ppm Wireless PRO

Aranet PRO CO2 Sensor for Wireless Monitoring

The Aranet PRO sensor pairs to an Aranet PRO base station over the Sub-GHz US920 band. CO2 reads from 0-9999 ppm at ±(30 ppm + 3%), and temperature reads 0-50°C at ±0.3°C. It also logs atmospheric pressure from 300-1100 hPa. An IP67 ASA-plastic enclosure lets it ride out the humidity of a working grow room.

Wireless CO2 Sensor for Greenhouse and Grow Rooms

Line-of-sight radio reaches up to 3 km, so one base station can cover a greenhouse range or a multi-room facility. At a 10-minute logging interval, a single AA runs the sensor up to 8.4 years before a swap. Set it at canopy height for the air plants actually breathe. Readings drop into the dashboard on a fixed schedule, so you can see exactly when CO2 injection fires. Pairing happens on the bench within 20 m of the base, then the sensor moves to its final spot.

Key Features

• 0-9999 ppm CO2: Reads carbon dioxide at ±(30 ppm + 3% of reading) with 1 ppm resolution.
• 0-50°C temperature: Reports temperature at ±0.3°C with 0.1°C resolution.
• Atmospheric pressure: Logs pressure across 300-1100 hPa at ±5 hPa alongside CO2 and temperature.
• 3 km line-of-sight radio: Sub-GHz US920 link carries readings to an Aranet PRO or PRO Plus base station.
• Up to 8.4-year battery: One AA runs the unit up to 8.4 years at a 10-minute logging interval.
• IP67 enclosure: Sealed ASA-plastic body holds up in humid, wash-down grow environments.
• XXTEA-encrypted data: Sensor-to-base transmissions are encrypted end to end.
