Description

Overview

Indoor air quality has become increasingly important to schools, businesses, and other organizations as they look to provide safe and comfortable environments.
MT15 is our highest performing air quality sensor, offering carbon dioxide monitoring for student and employee productivity. It monitors real CO2, TVOC, PM2.5, temperature, humidity, and ambient noise. It also offers a LED visual indicator to provide information about the air quality to the people in the room. Finally, the MT15 has flexible power options, including both a USB-C and PoE port on the device, which are positioned so that cables can be hidden. The MT15 can be installed in any space but will be particularly useful for monitoring air quality in classrooms and office settings where students and employees spend a large majority of their time performing activities that require cognitive effort.
Businesses need a complete view of data to make sound decisions. Businesses need visibility into their network availability metrics, capex & opex, and customer satisfaction levels to deliver on their mission. While businesses have a good grip on embracing and utilizing data in the business world, they have yet
to visualize the physical world fully.
Current solutions are complicated to install, do not scale and are difficult to use. Hence businesses do not have a simple and reliable way to have visibility into their critical assets to maximize their network uptimes, reduce equipment failure, reduce unnecessary site visits, and deliver best-in-class customer service.
So, Meraki is introducing a range of sensors to prevent loss and increase operational efficiency with ease. Our sensors are simple, scalable and secure. Our sensors also connect to the dashboard using the MV/MR, removing the need for expensive gateways. Customers can now gain real-time visibility into their
critical business environment from a single pane of glass.

Cloud Managed Sensors

The Cisco Meraki MT15 sensors provide temperature, humidity, CO2, TVOC, PM2.5 and Ambient Noise monitoring for environments across industries using BLE (Bluetooth Low Energy) beacons on the MR and MV.
Our sensors are built from the ground up to be easy to manage without compromising on power and flexibility.
All Meraki sensors are managed through an elegant, intuitive cloud-based interface. Meraki’s centralized management gives administrators granular visibility into their network

MT FAQ

Licensing

How does licensing work?

MT sensors require a dashboard license to operate, however, the licenses are not hardware-SKU specific. 

How does the free licensing work?

Similar to the free MV sense licenses, Meraki provides five free licenses for MT sensors to all new and existing organizations, and these licenses do not expire. Note that these licenses cannot be transferred to another organization in either co-term or PDL model.

Connectivity

How do MT sensors communicate with the Meraki dashboard?

MT sensors uses Bluetooth® Low Energy to communicate with Meraki IoT gateways. Supported IoT gateway devices are second-generation MVs and Wi-Fi 6 MRs. A full list of supported gateways is below.

MV MR
MV2, MV12(W/NE), MV22(X), MV32, MV72(X) Wifi 5 Wave 2 APs – MR33, MR42, MR42E, MR52, MR53, MR53E, MR74 and MR84
Wifi 6 APs – MR36, MR36H, MR44, MR45, MR46, MR46E, MR55, MR56, MR76, MR86 

WARNING: Environmental sensors are only supported with second-generation MV cameras and compatible MR APs.

Do MT sensors support Wi-Fi 5 (802.11ac Wave 2) APs as gateway?

Yes. The MT functionality was ported to support Wi-Fi 5 APs as a gateway. The minimum firmware requirement for MT support on Wi-Fi 5 APs is MR 28.6+. Please refer to the list of compatible gateways for accurate and up-to-date information.

How does the sensor connect to its gateway?

As long as the minimum requirements are met as per the MT Installation Guides and the sensor is within range of the gateway, it will automatically connect to any gateway that picks up the Bluetooth Low Energy advertisement of the sensor.

What happens when MTs can’t communicate with the Meraki dashboard?

MT sensors have onboard storage that will retain approximately the last five days of data. Upon reconnecting to the Meraki dashboard, all data points will be uploaded.

Sampling rate and frequency of connections

In order to conserve battery life, MT sensors are in sleep mode the majority of the time. They wake up at a set regular interval to connect and report  data to the gateway, which in turn uploads it to the Meraki cloud. Below is the sampling rate and connections per device type:

MT10 Data sampling: 2 minutes
Connection interval: 20 minutes
MT11 (w/temperature probes)

Data sampling: 2 minutes
Connection interval: 20 minutes

MT12 Data sampling: event driven
Connection interval: 20 minutes
MT20 Data sampling: event driven
Connection interval: 20 minutes

All sensors will wake up immediately if a configured threshold has been violated or if any event occurs in binary sensors like MT12 or MT20.

Deployment 

What firmware on MV and MR is required for MT to work?

MV MR

2nd Gen MVs – MV 4.8 +

MV2 – MV 4.17+

Wifi 5 APs – MR 28.5.1 +

Wifi 6 APs – MR 27.6 + 

Please refer to Managing Firmware Upgrades to schedule an upgrade.

 

How far can the MTs be placed from the MR/MV gateway?

MT sensors use Bluetooth Low Energy 4.2 to communicate with the gateway. Since Bluetooth Low Energy operates between 2.402 and 2.480 GHz, the range depends on the same principles as 2.4 GHz Wi-Fi. 

How many sensors can be used per gateway?

It is recommended to have a maximum of 32 sensors per gateway to ensure connection quality.

Minimum firmware requirement for a gateway to support 32 sensors:

MR – 28.5+

MV – 4.14+

Any firmware older than above only supports eight sensors per gateway.

Are MTs rated for outdoor use?

No, MT devices are designed for indoor use only. The MT12 is IPX5-rated (can resist a sustained, low-pressure water jet spray) and has a rubber liner to separate the power/battery compartment from being splashed or exposed to water. Still recommended NOT to submerge in water, as the rating states.

What are the supported temperature and humidity ranges for the MT10?

The temperature sensor supports 0°C – 55°C / 32°F – 131°F (accuracy: +/- 0.3°C) while using the included AA batteries. The humidity sensor ranges from 0-95%. That said, it is NOT an outdoor (IP67) or harsh environment-rated product. 

MT11 temperature probes supported range

Below are the specified temperature ranges of the MT11 temperature probes. Note that the operating temperature of the MT11 body is 0°C – 55°C / 32°F – 131°F.

Bare metal probe MA-CBL-TEMP-ME-1)
Range: -40°C – 55°C
Accuracy:
-10°C – 55°C = +/- 0.5°C
-30°C – 55°C = +/- 1°C
-40°C – 55°C = +/- 2°C

Glycol probe (MA-CBL-TEMP-GL-1)
Range: -40°C – 55°C
Accuracy:
-10°C – 55°C = +/- 0.5°C
-30°C – 55°C = +/- 1°C
-40°C – 55°C = +/- 2°C

Can MT10 be used to monitor temperature and humidity inside of a freezer?

The sensors are not IP rated and we do not recommend installing them inside of freezers.

Can the MT11 temperature probes be used to monitor temperature of fluids?

No. MT11 temperature probes are not rated to monitor temperature of any fluids, including water. 

Do the MT10/MT11 temperature sensors need to be calibrated?

No. The MT10 temperature sensor and the MT11 temperature probes use a digital sensor that comes pre-calibrated during the manufacturing process. This means no calibration is required during the product life cycle.

What part of the MT12 is capable of detecting water?

The full length of the cable can detect water as little as 3 mL. The included cable is 8 ft long, and can be extended to 16 ft with an optional second cable attachment.

How are the MT sensors powered?  

All MT products will come with AA batteries(Alkaline) included, and these batteries will last for about five years of powering the unit. That said, if you want a “permanent” powering solution, there will be a USB power adapter available at launch (MA-PWR-USB-XX) that can be used on the MT10 and MT12. The MT20 ONLY supports the battery operation. 

 Five years of battery life is projected based on the included 2.5V Alkaline batteries. Other types of batteries can be used, but the battery life may vary.

Alerting and Monitoring

What kinds of alerting does MT sensors support?

MT sensors support email, SMS, and Webhook alerts out of the box, no Twilio or similar integrations needed. It will also support push updates from the Meraki app. Please refer to the Sensor Alert Profiles article in order to set up alerting.

Do MT sensors support APIs?

Yes. Please visit Help > API docs on the Meraki dashboard for detailed documentation.
