Troubleshooting Sensors

The following guides you some troubleshooting that you can carry out if you feel that one of your sensors is not functioning properly.

Placement

Where a sensor is placed can have a direct impact on its performance:

• Do you see moisture (condensation, water, frost, or ice) or signs of corrosion...
  • On the outside of the sensor?
  • On the battery compartment?
  • In the batter compartment?

  If yes, you may need to replace the sensor as it has most likely been damaged by moisture.

  If the sensor is installed where it may be exposed to water, moisture, or icing, there are steps that you should take to protect the sensor before it is installed:

  • Installing Ezurio (formerly Laird) Sensors: Mounting the Sensors
  • Installing Milesight Sensors: Mounting the Sensors
• Is the sensor blocked by product? If yes,
  • Place the sensor where it is not obstructed by product.
  • Make sure there is airflow around the airflow sensor.
•  Is the sensor installed on the bottom of the equipment? If yes,
  • Move the sensor to be on a shelf, rack, or ledge in the middle or top of the equipment.
  • If possible, mount the sensor on an inside wall.

Connectivity

On the Dashboard, check the connection status icon on the sensor card for each sensor to make sure that the color is green or yellow. If red, then something is blocking the signal and it, or the sensor, needs to be relocated, including product.

• Working with Sensor and Checklist Highlights in the Mobile App
• Working with Sensor and Checklist Highlights in the Server App

Batteries

On the Dashboard, check the battery icon on the sensor card for each sensor to make sure that the color is green. If yellow or red, then the batteries needs to be replaced.

For more information, see Sensor Batteries, a section that contains many articles related to sensor batteries, including:

• Knowing When to Replace Sensor Batteries
• Before You Begin Replacing the Batteries

Alert System

It is recommended that you look at all sensor graphs on the Dashboard each morning to see what occurred over the past 24 hours, including:

• Were there any readings that were out-of-range, either above or below?
• Were there any gaps in the readings from the sensors?

If any of the above met alerting rules, then an alert should have been trigged and notifications sent out.

Also check those same sensor cards to see if alert notifications for any of the sensors have been paused.

For more information, see Sensor Alerts, a section that contains many articles related to the alert system, including:

• Understanding Sensor Alerts and Notifications
• The Dashboard graph shows the sensor was out of range. Why didn't I receive an alert notification?

Accuracy

All sensors are calibrated at the factory before they are shipped. There is no field calibration available.

If you want to check the accuracy of a sensor, carry out the following:

1. Place the sensor in a location along with one or more other sensors, such as on a prep table.
2. Allow the sensors to sit for at least 30 minutes.
3. Check the cards for each sensor on the Dashboard and note the most recent temperature reading.

All sensors on the table should be reporting the same temperature to the Dashboard:

• If all sensors report the same temperature, then there is no issue with accuracy.
• If you checked two sensors and they don't match, test again with 3 or more sensors to see which of the original two may be inaccurate. The one that does not match the others may have an issue. Contact ComplianceMate Support.
