  • Can I use NEO in a refrigerator, freezer, or walk-in cooler?
    Yes, however we recommend that you use the probe version NEO-1P  or NEO-1DP of our sensors to maximize the life of the battery.
  • Do we have any control over the battery life of a Sensor ? Where/how?
    In the App or on the cloud BLE Polling Time can be set in the Advanced Settings.

    The Polling Rate represents how often the element is checked. For example, if the NEO-1P Temperature sensor polling time is set to 15 seconds, every 15 seconds the Temperature is read and checked for any alerts.  If an Alert has been trigged, the user is immediately notified.

    Having a high polling rate but a very low sample rate allows the system to quickly detect changes in a sensor without the need to record the value frequently (Sampling time) or transmit to the cloud (Check in time).

    BLE Sampling Time:  The Sample Rate represents how often the data value is saved on the sensor. For example, if the NEO-1P sampling time is sent to 15 min, every 15 minutes the temperature is saved on the device and will be sent to the cloud based on the scheduled check-in time. Depending on the sensor, ~100,000 data points can be saved.
    Have a low sample rate allows the system to log more data and helps with battery life. All data points saved will be sent to the cloud based on the check-in time. The more data required to be sent,  the lower the battery life.

    BLE Check in Time: The check in time represents how often the stored data (sample Time) is transmitted to your account on the iMatrix Cloud. For example, if you need a report every 4 hours for HACCP compliance for your refrigeration units, we suggest you save the data every hour (Check-in : 60 Minutes)

  • How do you turn the Sensor off? How do you reset the device?
    To Turn on the sensor, push the button on the rear once.  The LED on the front will momentarily flash blue, indicating the unit is on.
    To Turn OFF the Sensor, press the button twice in 2 seconds.  The LED on the front will momentarily flash green and then red, and the sensor is OFF.
    To Reset, hold the button on the back for ~ 4 seconds, and the LED on the front will blink, and the unit will restart in a few seconds.
  • NEO-1

  • How often does the sensor take readings?

    The NEO-1 sensors have adjustable sensor readings. You can choose to have sensors take readings every few seconds, or even just once a day. However, the more infrequent the readings are, the longer the battery life will last.

  • NEO-1P

  • Can stil access my data wirelessly?

    Yes, the sensor will still transmit temperature readings just as the NEO-1 will. The sensor uses bluetooth technology to connect to your wireless gateway and uploads your information to the cloud.

  • How can I check the accuracy of my readings?

    One way to verify the accuracy of your data is by comparing it to a known temperature. A 50/50 mixture of ice and water will be freezing, at 32 degrees. Placing the probe in this solution should show a temperature reading of 32 degrees.

  • How do I get the NEO-1P to add data to my account?

    You can add sensors with either the QR code included on the back of the sensor, or add the sensor by serial number. If using the mobile app, you may also choose to use ‘guest’ mode to start receiving data immediately.

  • How often does the sensor take readings?

    The NEO-1 sensors have adjustable sensor readings. You can choose to have sensors take readings every few seconds, or even just once a day. However, the more infrequent the readings are, the longer the battery life will last.

  • Is it safe to fully submerge my sensor in water?

    The main sensor body should not be submerged in water. However, the extension probe attached to the sensor may be fully placed in liquids.

  • What if my readings aren’t accurate?

    If your sensor isn’t showing the correct readings, you can calibrate your sensor through the mobile app. Click on the specific sensor and choose calibrate. Take note of the current readings, and enter that figure in the first space. In the second space, enter the known value (i.e. ice water would be 32 degrees). Then, confirm the changes and refresh your screen to see the new readings.
