Elsys ERS VOC Smart Building Sensor

Part of the ERS range, Elsys' VOC sensor is aimed at measuring the indoor environment in homes, offices and smart buildings. The discreet sensor is designed to be wall mounted, ERS VOC is completely wireless. Powered by two 3.6V AA lithium batteries (not included), the sensor can run for up to five years.

The device features sensors for measuring Volatile Organic Compounds (VOCs), temperature, humidity, light, and motion. The reporting intervals can be set by a free Android app, or changed via LoRaWAN downlinks.

Updated: We now stock the latest version of the sensor, this includes LED traffic-light indication. This can be configured to flash red when the VOC level is too high, amber to warn it's getting high, and green when it's in a safe range. The LED is actually configurable to display the state of any of the sensor parameters, giving flexibility in how you can make use of this.

Don't need the PIR sensor? See the Elsys ERS CO₂ Lite for the low-cost Lite version.
