Site Checklist

• Internet Access – Ensure the location has access to a stable Ethernet or Wi-Fi connection.

• Debris Sources – Keep away from dust vents, dense foliage, or anything that may skew the readings.

• Airflow – Avoid vents, fans, AC units, or anything that could blow particles directly into the sensor.

• Obstructions – Choose an open space, away from walls, trees, or large furniture that may block airflow.

• Moisture Risks – Stay clear of areas exposed to water spray (sprinklers, fountains, humidifiers, etc.).

• Traffic – Avoid high foot or vehicle traffic to reduce tampering and contamination.

• Stable Mounting Surface – Make sure the mounting surface is solid and free of vibrations.

• Security – Consider using a small lock if tampering is a concern.

Note: If you are unsure of where to deploy your sensor, please reach out to us via email to support@pollensense.com. One of our technicians can help you decide on the most optimal location you have available.

Site Assignment & Cluster Creation

Sites and Clustering:
A Site is a physical location you define where a sensor collects and uploads particulate data. This data is permanently tied to the Site where it was collected and does not move with the sensor.

You can view Site data at portal.pollensense.com under the Organization tab.

A Cluster has improved accuracy as you can assign multiple sensors to a single Site. Sensors in a Cluster must be placed side by side, no more than 1 meter apart.

For instructions on assigning a sensor or Cluster to a Site, see Site Assignment via Particle Sense.

Selecting the Correct Provision Type

When assigning your sensor to a Site, it’s important to choose the correct Provision Type to ensure accurate data reporting. Use the chart below to determine the appropriate option:

Note: Additional Provision Types are available but require approval from a Pollen Sense Technician before use.

Starting and Stopping Sampling

Once your sensor is assigned to a Site, it's ready to begin collecting data.

1. Check the media cartridge: Ensure the media cartridge (tape cassette) is properly seated by applying light pressure to the center circle.

2. Start sampling: In the Particle Sense app, open the sensor’s Manage page and toggle Collect Samples to On.

   1. It may take a moment to update—pull down to refresh if needed. Once sampling begins, you’ll hear the internal fan and see the tape start to advance.

3. View collected data: Images and particle counts are viewable at portal.pollensense.com under the sensor’s assigned Site.

4. Stop sampling: When you're done collecting data, toggle Collect Samples to Off in the app, and remove the sensor from its Site if needed.
