MT14 Installation Guide - Indoor Air Quality


The Cisco Meraki MT14 is a cloud managed Air Quality Sensor sensor that is exceptionally simple to deploy and configure due to its integration into the Meraki dashboard and the use of BLE technology. The MT family eliminates the complex and costly setups required by traditional solutions which removes the limitations of placement of these sensors. 

Pre-Installation Preparation

You should complete the following steps before going on-site to perform an installation:

Configure Your Network in the Dashboard 

The following is a brief overview of the steps required to add an MT sensor to your network. 

  1. Log in to If this is your first time, create a new account.
  2. Find the network to which you plan to add your sensor, or create a new network.
  3. Add the sensors to your network. You will need your Meraki order number (found on your invoice) or the serial number of each sensor, which looks like Qxxx-xxxx-xxxx, and can be found on the back of the unit or included in the box.
  4. Add the gateway (MV or MR) to the same network as the sensor.


Make sure the gateway is in the same network and is online and operational. If the sensors are powered on without a functioning gateway in the immediate vicinity, the sensors will consume power at a high rate until it finds a gateway.

Quickly Scan and Claim Multiple Devices through the Meraki Mobile App 

If you have to claim multiple devices, the quickest way is by scanning their barcode using the Meraki app.

  1. Log in to your Meraki iOS or Android app with your Meraki dashboard account. Create a new account if you do not have one.
  2. Navigate to the correct network through left-side bar.
  3. Go to the Devices tab from the bottom navigation bar.
  4. Select the + icon on the top right of the screen and pick Scan new device barcode.
  5. Point your phone camera toward the hardware barcode to claim the device.
  6. Enter device information and then select Done. Press Add another to claim a new device.

Installation Instructions

General Guidelines

As the MT14 helps monitor the ambient air quality metrics, The following tips and guidelines should be considered when positioning your MT14:

  • Mount the sensor about 6-8 feet from the ground. This will help the sensor monitor the air quality at the average height of human breath.
  • Make sure the MT14 is away from an inlet or an air vent. Higher air flow near the sensor can result in inaccurate readings.
  • Ensure that the MT14 sensor is oriented in an upright position with the vents facing downwards. This is to make sure the airflow for PM2.5 sampling stays constant.

For installation guidelines when using High Sampling Mode for Vape detection, please refer to this article.

Operating Modes

The MT14 sensors have 2 operating modes:

  1. Battery Powered - Requires 4 AA batteries to power on the sensor and collects the Temperature, Humidity, TVOCs and Ambient Noise telemetry data
  2. USB-C Powered - Requires a 5V;0.2A USB-C power adapter to power the sensor. This mode enables PM2.5 sampling.
  3. High Sampling mode - Requires external power. This mode enables faster sampling rates for PM2.5.

Supported USB-C Accessories: MA-PWR-USB-X and MA-PWR-ETH 

Mounting Instructions

For most mounting scenarios, the MT14 has flexible options to provide quick and simple mounting. The instructions are as follows:

  1. Decide the operating mode for the MT14 before mounting the unit
    1. For battery-powered mode, remove the pull tab near the battery compartment to power on the device. The batteries are preinstalled and removing the pull tab will power the sensor.

  1. For USB-C Power mode, connect the USB-C power supply on the right side of the sensor


NOTE - It is important to ensure that the sensor is oriented in the upright position for PM2.5 sampling to accurately collect data.

  1. In order to mount the sensor on different locations, there are 3 options
    1. Screws - The mounting plate can be directly screwed onto the wall
    2. VHB Tape - Double-sided VHB tape can be used to stick the mounting plate on any type of surface.
    3. Magnet - Stick the magnet on any surface and the mounting plate can be stuck to the Magnet.

Once the mounting plate is on the desired surface, slide the MT14 sensor onto the plate and use the included Torx screw to secure the sensor.
