PassiveLogic® Sense Nano™ sensors will be installed wirelessly. You will use the PassiveLogic Lens™ app to view your digital twin and guide you to where your sensors are to be installed and provisioned. This digital twin is deployed, meaning that the building is operational and can’t be edited. However, you can communicate with and provision the sensors in the model, then view data from the live sensors in the Live™ Analysis mode.

For information and tips about navigating the digital twin model in Lens, see “Navigating the Digital Twin in Lens.”

Sense Nano installation tips

Gather the following components and tools for this installation:

• Sense Nano sensors
• Wall mounting brackets with removable adhesive strips
• iPhone Pro/Pro Max with Lens installed
• Tools: Bubble level, pencil, measuring tape, wall cleaning supplies

Physically installing a Sense Nano

To install a wire-free Sense Nano sensor on the wall:

1. Open the Lens app on your iPhone.
2. Navigate to the digital twin building, then tap the floor of the Sense Nano sensor you want to install.
   Note: In this documentation we use the PassiveLogic office digital twin for many of the screenshot examples.

3. Find the sensor you want to install, then zoom in to its location.
   In iOS, pinch to zoom (move two fingers apart or together on the screen to zoom in or out).
   
   

   The gray (not provisioned) sensor icon represents where the sensor is placed in the digital twin and corresponds to where it should be physically installed.

   Tip: For sensor and sync icon details, see "Sensor and profile icon states in Lens."
   Once the Sense Nano sensor is installed on the wall, you will return to the Lens app to provision it.

4. Using the placement information in the digital twin model and the following guidelines, identify and mark the best location for the sensor with the measuring tape and the pencil.

   Guideline	Details
   48 in (1.22 meters) from floor	This is the typical recommended height for sensor devices.
   Clean and dry	Be sure the location for the sensor bracket is clean and dry.
   In a well-lit area Not in direct sunlight (year round)	For wireless Nano installations that require light to keep the battery charged. Direct sunlight can cause the Nano to overheat.
   In conditioned, indoor areas (heated, cooled)	Interior spaces that maintain the supported environmental conditions of 32 to 113°F (0 to 45°C).
   Away from heat sources and the direct path of ventilation	Being too close to coffee pots, heating elements, other heat sources, or in the direct path of heating or cooling sources can cause false temperature readings.
   Away from exterior windows, walls, and doors	Being too close to exterior windows, walls, and doors (outside air openings) can cause false zone temperature and humidity readings.
   Not behind doors, curtains, or dividers	These locations can prevent or delay the sensor from sensing zone environmental data and can reduce the accuracy of average readings.

   
    

5. Use a bubble level to draw a horizontal line a little less than width of the mounting bracket
   (1²/₃ in / 4.24 cm).
   
   Tip: We recommend marking the bracket dimensions on your level in advance as a guide for drawing the level line the proper length. The purpose is to avoid seeing the level line once the sensor is installed. To do this:
   •   Place the Nano mounting bracket on the top of the level.
   •   Mark on the level at each outside edge of the bracket (with a pencil so it can be erased). (Alternatively, you can make two marks on the level about 1²/₃ inches apart.)
6. Get a Sense Nano sensor and a wall mounting bracket.
7. Remove the adhesive backer from the strips on the back of the mounting bracket.
   Important: If using the adhesive that is the same size and shape as the bracket, be aware that it is very difficult to remove once installed.
8. Carefully align the mounting bracket notches to the level line, then press the bracket firmly to attach it to the surface.
   
   Note: If you are using the strip style adhesive, move the adhesive strips out of the way as needed. Don’t cut or tear the ends of the strips that come out to the front of the bracket. They are necessary for bracket removal.
9. Align the PassiveLogic Jewel logo at roughly 11 o’clock, place the slots in the Nano on the mounting bracket tabs, then twist the Nano clockwise to 12 o’clock until it locks with a click.
   

Continue to the next section to provision the sensor using the Lens app.

Optional: To remove a Sense Nano device from the mounting bracket, see “Sense Nano: Removal.”

 

Provisioning a Sense Nano

After installing a Sense Nano sensor, use the Lens app to connect to the sensor and provision it to make it live in the digital twin model. Once provisioned, you can reconnect to the sensor to view live data as well as viewing data in the PassiveLogic Quantum™ cloud, in the Live™ web app.

To provision a Sense Nano sensor with the Lens app:

1. In Lens, open your building project, select the floor where you would like to install a Sense Nano device, and tap the gray icon that represents an un-provisioned sensor.
   The Unnamed sensor card will open.
   Tip: For sensor and sync icon details, see “Sensor and profile icon states in Lens.”
2. Tap Provision on the sensor card.The Diagnostics screen opens.
3. Align the hexagon on the screen of your iPhone with the hexagon of the PassiveLogic logo on the Sense Nano until their edges are aligned.
4. Once aligned, tap the Provision button at the bottom of the screen.
   Your phone will flash its light to communicate with the sensor. Do not move your phone during this process.
5. Hold your device camera steady to keep the hexagons aligned until the hexagon on screen turns fully orange and Finding appears on screen.
   The orange outline returns and will build around the hexagon on the screen. The sensor will flash to signal that it is connected and provisioning.
   
   Once the provisioning process is complete, your iPhone will connect to the Sense Nano sensor, and the app will enter the monitoring screen. Seeing data populate on your screen is verification that the sensor is provisioned and working.
   

Note: When you first connect, you may see an ellipsis ··· in the parameter blocks temporarily, but this should fill in with the measured values once the data begins to stream.
In this view you can do the following:

• Tap a square to select the type of data displayed on the graph.
• Tap the Interval menu to select the desired cached data time interval.

Live shows you data from the time you connect to when you tap Done, for up to 5 minutes.
