This device is capable of connecting to a cloud-based dashboard through a simple, ubiquitous WIFI network, without the need of additional hardware – as other connected monitors do. It also incorporates an innovative self-calibrating functionality that ensures accuracy, longevity and reliability. The device is fully designed and made in the UK, and it is fitted with a real, professional-level CO2 sensor, as opposed to other devices that only provide eCO2 (estimated) concentration values.
As with everything we do, our Carbon Dioxide Monitor is fully designed, developed and manufactured in the UK, with all key electronic components also sourced locally.
Sensor IT’s Carbon Dioxide Monitor presents CO2 concentration in the air, and other ambient data, to the user through a graphical dashboard showing a number of parameters that include:
The Monitor also displays historical data graphically on CO2 concentration, taking a sample every six minutes, covering a period of several hours in total.
The monitor implements full WIFI connectivity and can send data in real-time to a cloud-based dashboard.
Through a full graphical dashboard, visual, centralised data can be monitored across entire buildings or zones. The data can also be accessed through a mobile App, compatible with Android and iOS.
NOTE: dashboard requires access fee.
Examples of CO2 concentration and the correspondent Air Quality are provided below.
Normal background concentration in outdoor ambient air. This concentration can only be achieved with extremely good ventilation
Concentrations typical of occupied indoor spaces with very good air exchange
Good air quality. If possible, it is advised to keep the concentration closer to the lower limit
This concentration indicates that the air is starting to get stale and needs ventilation
Poor air quality. Rooms with this concentration should be ventilated with fresh air as quickly as possible
Very poor air quality. The room urgently needs fresh air
This device implements a professional-level, industrial-grade sensor, based on a patented self-calibration logic. This logic virtually eliminates the need for manual calibration in applications where the indoor CO2 level drops to outside levels during unoccupied periods (e.g. during evening hours). This described logic is a special software routine in the sensor that remembers the background readings for 14 consecutive evenings, calculates if there is a sensor drift, and then corrects for it. The sensor will typically reach its operational accuracy after 25 hours of continuous operation at a condition that is exposed to ambient reference levels. Sensors will maintain accuracy specifications with the self-calibration logic enabled, given that it is at least three times in 14 days exposed to the reference value and this reference value is the lowest concentration to which the sensor is exposed.
The device conforms with Sensor IT’s Open Architecture Design (SOAD), which introduces a new and innovative concept for Internet of Things devices. This brings a new level of adaptability and customisation to everything we design and manufacture whereby they can be customised to meet particular requirements, as put forward by our customers.
The Air Quality Agent could, for instance, be redesigned to integrate with the customer’s monitoring, or even their SCADA, systems, with the data transmitted adapted to their specific communication protocol.
