Capteurs de CO₂, de température et d'humidité

These three factors work hand-in-hand to define indoor comfort and wellbeing. High CO2 levels signal poor ventilation, while temperature and humidity affect comfort, health, and even equipment performance. Monitoring all three ensures commercial spaces remain safe, comfortable, and energy-efficient.

The sensor is designed for reliable commercial use and provides readings within the below ranges:

• CO₂ readings within ±125 ppm.
• Temperature within ±0.5 °C.
• Humidity within ±5%.

This level of accuracy ensures data you can trust for decision-making around ventilation and building management.

The device uses ultra-low power and energy harvesting technology with:

• A built-in solar cell to harvest energy from ambient room light.
• A lithium backup battery (3.6 V A-size) for low-light conditions. Battery life is up to 10 years, depending on light availability and reporting frequency.

• Solar powered mode: sends readings every 5 minutes.
• Battery backup mode: sends readings every 15 minutes to conserve power. This ensures reliable monitoring while optimising power efficiency.

Our CO2, Temperature and Humidity sensors use the EnOcean wireless protocol (EEP: A5-09-04) and can transmit data up to 30 metres indoors and up to 300 metres in open space, allowing flexible deployment across different building types without Wi-Fi or hardwiring.

The sensor features automatic CO₂ calibration every 8 days to maintain accuracy. Manual calibration is also possible via the DIP switch and “learn” button. Thanks to the solar-assisted power and low-maintenance design, ongoing upkeep is minimal.

The sensor is compact (115 × 80 × 35 mm), discreet, and supplied with a wall-mounting backplate. Installation requires no complex wiring, and the sensor begins transmitting measurements within seconds once fitted and powered on.

Yes. Data is transmitted securely via the EnOcean wireless protocol and accessed through a Pressac Smart Gateway. The data transmitted by our sensors can be integrated into platforms such as MQTT, Azure IoT Hub, AWS IoT Core, IBM Watson IoT, and Google Sheets, giving you complete flexibility with no vendor lock-in.

Yes. The sensors are designed for scalable deployments, from individual rooms to entire campuses. Data from multiple devices can be centralised and analysed in real time, helping to monitor air quality and comfort across diverse spaces.

Yes. Due to their simultaneous monitoring of CO2, temperature and humidity, our sensors can support compliance with building regulations, energy efficiency frameworks, and wellbeing standards such as WELL or RESET, making them valuable for both facilities management and employee health.
