Troubleshooting

LED Blink Codes

When you power up the Sensor System, the "STAT" LED should blink once or twice, then stay solid red. If it remains blinking, you can count the number of blinks to determine the problem:

1. If the red LED blinks ONCE repeatedly (on/off), there's a problem with the microSD card. Remove power from the Sensor System, remove and replace the microSD card, and try powering it up again. If you continue having problems, you might try a different microSD card, or reformat the one you have (see below).

2. If the red LED blinks TWICE repeatedly (on/on/off), there's a problem with the Combo Environmental Sensor or its cable. Remove power from the Sensor System, disconnect the Sensor, and ensure that the connectors and sockets are undamaged. Then re-connect the sensor and try powering it up again. If you still cannot get the sensor to work, you may need to replace the sensor and/or cable.

Reformatting the MicroSD Card

If the microSD card refuses to work, you might try reformatting it with your computer. Note that you normally shouldn't need to do this; the microSD card comes preformatted and ready to use.

Formatting instructions vary by computer and operating system. The general steps are:

1. Insert the microSD card into one of the adapters (USB card reader or full-size SD card), and insert it into your computer. It will show up as a new hard drive.

2. Select the proper drive in your computer's "File Explorer" or "Finder" window.

3. Choose "format" from the drive options.

4. Ensure that "FAT32" is selected as the file system type.

5. Start the format.

6. When it is done, safely remove the card from your computer, and proceed with the Sensor System instructions above.
