CO₂ Sensor

THE BATTERY-POWERED IoT SENSOR
THAT ALLOWS YOU TO MEASURE
THE CONCENTRATION LEVELS OF CARBON DIOXIDE.

GENERAL OVERVIEW

The Sick Building Syndrome indicates a well-defined symptom picture, which manifests itself in a large number of buildings equipped with mechanical ventilation and air conditioning systems, without the introduction of fresh air from the outside.

Since, in this scenario, health or comfort problems are related to inadequate ventilation, it is necessary to intervene with adequate control systems and functional sensors.

The CO2 sensor developed by Filippetti Group ensures the highest levels of comfort in terms of IAQ (Indoor Air Quality), measuring the concentration of carbon dioxide present in indoor environments (with a range of 350 ÷ 2000 ppm). The device monitors the air quality and interacts with the ventilation system, in order to guarantee correct levels of environmental comfort.

The measurements carried out, together with the intelligence on board the IoT Smart Platform and the integration with HVAC, allow optimal control of the area in indoor environments.

MAIN ADVANTAGES

Accurate and precise – the sensor allows accurate measurement of data on the concentration of carbon dioxide in the air, with an accuracy of ± 50 ppm (± 3% of reading)
Perfect aesthetic integration with the environment – the small size, the modern lines and the battery power supply that eliminates the need for wiring, make it the ideal solution in any environment.

OPERATING PRINCIPLES

COMMUNICATION: SMART NETWORK PROTOCOL

The device acquires the air quality data (CO2) and sends them to the Filippetti Group Gateway using the proprietary Smart Network protocol and UHF wireless communication (LoRa/FSK modulation).

SPECIFIC MEASURES: CO2

The sensor integrates a 16 bit ADC, with which it is possible to make measurements with good resolution and accuracy (± 50 ppm), in a range between 350 and 2000 ppm.

ACTUATION:

The device itself does not carry out implementation. However, it provides the data necessary for the Filippetti Group IoT Smart Platform, which integrates various intelligence systems on board, and is able to send commands (e.g. ignition of the aerator) to third-party devices.

POWER SUPPLY: by BATTERY

The device is powered by 3 primary AA batteries of lithium thionyl chloride (nominal voltage of 3.6 V, 2.2 Ah each). Under standard use conditions (sampling frequency and data transmission equal to 5 minutes), it can guarantee a continuous average operation lasting 3 years.
