EnOcean Wireless CO2, Temperature and Humidity Sensor

Measure the indoor air quality in each room or zone

Our wireless multi-sensors measure and monitor the carbon dioxide (CO2) levels, ambient temperature and relative humidity in a room or zone. The small wireless CO2 sensors simply stick onto the wall and are solar-powered using ambient room light, making them easy to install and very low maintenance.

See live indoor environment quality
Access live data to get an instant view of ambient conditions in each room

Monitor conditions in each room over time
Measure conditions in each room or zone to see how conditions change through the day

Implement demand-driven control
Feed live data into your building management system for demand-driven HVAC control


  • Small, discreet sensors simply stick to the wall
  • Measures ambient carbon dioxide (CO2), temperature and relative humidity:
    • CO2 0-2550PPM (accuracy +/- 125PPM)
    • Temperature 0-51ºC (accuracy +/- 0.5ºC)
    • Humidity 0-100% RH (accuracy +/- 5%)
  • Reports every 5 minutes when solar-powered or 15 minutes
    when battery-powered.
  • Solar-powered using ambient room light – optimally angled
    to absorb light – with a battery back-up for periodic
    low-light conditions. Batteries typically last up to 10 years
  • Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
    • 868 MHz for Europe (RED)
    • 902 MHz for North America (FCC) and Canada (IC)
    • 928 MHz for Japan (ARIB specification)
  • EnOcean Equipment Profile (EEP): A5-09-04
  • No recurring fees. Access the data through your chosen platform, without any additional costs from Presssac.
