INDOOR AIR QUALITY MANAGEMENT USING RASPBERRY PI AND …

research, we have developed an air quality sensor system using CO 2, CO, Dust sensors. We have chosen only these gases as these are the major pollutants that affect the indoor air quality. Along with these, we have used a Temperature and Humidity sensor to view the changes that take place in the concentration of CO 2, CO, dust in the air with the changes in temperature, humidity or the number ...

CO2 sensor, air-conditioning and Central Control System ...

The indoor sensors are less resilient and therefore their housings have IP20 protection class, while the external sensors are exposed to a variety of weather conditions, so their housing is protected by IP65 protection class. A CO2 sensor is also used in our homes alongside industry. Room ventilation systems, cooling or heating devices and any other new and modern energy-saving systems use many different sensors. Among the other sensors, even CO2 sensors …

Monitor CO2 levels indoor with our sensors | Senseair

The CO 2 concentration in the room will then increase for each person added. Therefore, a small Demand Controlled Ventilation system can be a good idea. This system has a sensor that measures the CO 2 value and sends a signal to a ventilator or a VAV-device that then changes the level of ventilation required in the room. The system also has variable dampers that are usually used to regulate the airflow through the sensor.
