Elsys ERS Display CO2 Lite LoRa

Monitor indoor air quality with laboratory-grade precision using the ELSYS ERS Display CO2 Lite, featuring an NDIR CO2 sensor accurate to ±30 ppm ±3% of reading. This LoRaWAN-enabled device tracks carbon dioxide, temperature, and humidity, displaying real-time values on a crisp e-ink screen for effortless readability.

Overview

The ERS Display CO2 Lite is engineered for continuous environmental monitoring in offices, schools, healthcare facilities, and smart buildings. Its non-dispersive infrared (NDIR) sensor delivers reliable CO2 measurements from 400 to 5000 ppm, while integrated temperature and humidity sensors provide complete climate data. The e-ink display offers high contrast and low power consumption, ensuring visibility even in bright conditions.
