AJAX Sensor LifeQuality White

Description

LifeQuality is a smart air quality monitor with CO2, humidity and temperature sensors that helps evaluate the dynamics of air quality at home, in the office, in the workplace or in any other space.
Users get medical-grade measurement accuracy, comprehensive in-app information, and automation scenarios.
An Ajax security system with LifeQuality turns on ventilation or humidifier if the air quality indicators are below comfortable.
