Setup

You can register the E2 sensor via BLE through the mobile app. Here is where you can see how to register/unregister the E2.

Dashboard

The E2 dashboard provides an in depth overview of what the E2 is capturing. On this page you can change the name of the sensor, view system measurements, and see real time if any of them are above an unhealthy threshold.

Change Sensor Name: To change the name of a sensor simply click the pencil icon next to the breadcrumb at the top of the screen (below).

System Measurements: You can view all the system measurements in one area (below). Items listed as "Undetected" will change to "Detected" if detection events occur. A more detailed explanation of what each measurement entails can be found in the Measurements section of this article.

Timeline View: You can view events that the E2 picks up on the timeline view. Similar functionality to how our camera events can be viewed, you can simply click on an event marker on the timeline and that will take you to the selected event. If you have a camera linked to the E2, then the camera footage will start to play when you click on an event.

Historical Data: You can view graphical data captured by the E2 within this section. From here, you can select the time duration (right side of below screenshot) of the data to be displayed as well as download this data to your local machine.

By selecting the dropdown on the left side of this view you can toggle between which type of measurement you want to see the historical chart for (below).

Settings and Details: Within the "Settings & Details" tab you can do the following:

Change sensor name
Change sensor location
Change sensor policy
Unregister the sensor
Associate the sensor with a camera

Measurements

Temperature

There are two temperature readings the E2 provides. One is a temperature the sensor it self reads, and two is the external probe sensor that you can place in a different location from the E2.

Temperature: -40 to +125°C (-40 to +275°F)

Humidity

Humidity is the measurement of moisture in the air. Higher humidities tell us there is a lot of moisture in the air where as lower humidity levels signify dryer air.

Humidity: 0 - 100%

Air Quality

This measures the quality of the air around the sensor. Higher values can mean there is a fire or unhealthy air near by. To learn more about this standard visit here.

IAQ
"Bad": 5+
"Poor": 4 - 4.99
"Medium": 3 - 3.99
"Good": 2 - 2.99
"Very Good": 0 - 1.99

Ethanol Parts Per Million (ppm)

This measurement measures the concentration of ethanol in the air. Detection of ethanol can mean there are harmful compounds near by which could come from events such as a leak. Parts per million (PPM) is a unit of measurement used when expressing a very dilute concentration level of pollutants in the air, water and other fluids.

Ethanol ppm
"Detected": 0.4+
"Undetected": 0 - 0.3

CO2 Parts Per Million (ppm)

Carbon Dioxide detection is critical as consuming too much of this gas can be fatal. Parts per million (PPM) is a unit of measurement used when expressing a very dilute concentration level of pollutants in the air, water and other fluids.

CO2 ppm
"High": 3000+
"Medium": 1800 - 2999.9
"Low": 1000 - 1799.9
"Undetected": 400.0 - 999.9

TVOC

TVOC stands for Total Volatile Organic Compounds. Volatile organic compounds (VOCs) are compounds with high vapor pressure and low water solubility. This means these substances won’t join to themselves (volatile) or are water solvent (organic). Volatile organic compounds are harmful air pollutants that evaporate under household conditions.

TVOC mg/m^3
"High": 9.0+
"Medium": 3.0 - 8.9
"Low": 1.0 - 2.9
"Undetected": 0 - 0.9

Particulate Matter (PM)

PM2.5 refers to particulate matter with particle diameter up to 2.5 microns. PM2.5 particles can travel deep into the human lung and cause a variety of health issues.

PM 2.5 µg/m^3
"High": 150.5+ 
"Medium": 35.5 - 150.4 
"Low": 12.1 - 35.4 
"Undetected": 0 - 12.0

Vape Smoke

Vape smoke is smoke emitted by vaporizers. The E2 can detect vape smoke within a 144sq ft area.

Vape Smoke
"Undetected": 0%
"Detected": > 0%

Alerts

Setting up alerts for the E2 can be done by modifying the policy assigned to it. To learn more about configuring policies visit our article here.
