ERS CO2 Carbon Dioxide Sensor (For Use in Schools and Offices)

Overview

The Elsys ERS CO₂ is a sensor designed for measuring indoor air quality parameters including carbon dioxide (CO₂), temperature, light, motion and humidity. It is designed to be wall-mounted and comes enclosed in a minimalistic and discreet room sensor box.

LoraWAN Certified™, the wireless ERS CO₂ sensor is battery operated and can be used anywhere where the monitoring of the indoor environment and air quality are essential including workplaces, schools, hospitals, aged care facilities, and more.

Wireless functionality – ERS CO₂is completely wireless and powered by two 3.6VAA lithium batteries.
NFC enabled for easy configuration – The sensors in ERS CO₂ come equipped with NFC for easy configuration with an Android device. You can change the sample rate, data rate, encryption keys, triggers activation and much more.
Long-Lasting Battery – The device has a battery life of up to 10 years.
Automatic Calibration Routine – The CO₂ sensor has an internal automatic calibration routine. This routine calibrates the sensor to set 400 ppm to the lowest value that has been read in the last period of approximately 8 days.
LoRaWAN Certified - Being a LoRaWAN CO₂ sensor it is self-contained and transmits at low data rates of large distances to a local gateway enabling installation anywhere in the building.
Motion Detection Sensor - It also detects motion with a passive infrared camera
Traffic Light feature - A traffic light feature will let you know when a certain threshold of CO₂ levels has been reached.
