MT14 Datasheet - Indoor Air Quality Monitor



Indoor air quality has become increasingly more important to schools, businesses, and other organizations as they look to create smart, sustainable buildings that provide safe and comfortable environments to people. Poor air quality, on the other hand, can decrease productivity or cause adverse health effects ranging from mild to severe. 


The Cisco Meraki MT14, part of the Meraki MT sensor portfolio, provides real-time indoor air-quality monitoring to promote smart spaces and create safe environments. MT14 can detect the presence of chemicals, debris, extreme temperature, humidity, and noise. If air quality decreases for any reason, MT can notify you immediately or automate the building HVAC system to increase ventilation and keep people safe.

Smart sensors. Smarter businesses

Meraki MT sensors accelerate deployment, simplify management, and provide data-driven business outcomes. Flexible mounting, battery or wired power options, and automatic Bluetooth® pairing make it easy to provision thousands of sensors in a short amount of time. Centralized cloud management enables MT sensors to be managed alongside other networked devices, while open APIs allow MT to integrate with any business system.
