Model E-Lite: Connected air quality monitoring sensor

Complete air quality monitoring system with CO2, VOC (index), particulate matter, barometric pressure, temperature and humidity sensors all in one.

Without Wi-Fi or when Wi-Fi is deactivated, the sensor records the measurements in its internal memory so that they be uploaded to the cloud portal when Wi-Fi is available again or activated.

Free access to the cloud portal.

Features

• CO2 measurements using dual-beam NDIR technology (Sensirion SCD-30)
• Particulate matter measurement (Sensirion SPS30)
• VOC Index (Sensirion SGP-40)
• Barometric pressure (Bosh BMP180)
• Wi-Fi connectivity (2.4 GHz only)
• About 4 hours of battery operation (with Wi-Fi off)
• 48 months of data retention in the cloud portal
• Possibility of an audible alert when the CO2 level exceeds a configurable threshold
• Charging via USB-C port
• Ability to update firmware remotely (Over-The-Air)
