iMETOS Maintenance & troubleshooting 8
6. SOIL TEMPERATURE SENSOR
6.1 Maintenance
The soil temperature sensor does not need any maintenance. If it fails it is nearly always due to damaged wires.
6.2 Troubleshooting
• Sensor shows values out of range: water entered in the sensor – sensor should be replaced.
• Gap of data: cable might be damaged, this increases power consumption and it can lead to misfunction on
the station – unplug the sensor and replace it.
7. GLOBAL RADIATION SENSOR
7.1 Maintenance
The global radiation sensor should be maintained cleaned. A visible check at the plastic cover is recommend-
ed at the beginning of the season.
7.2 Troubleshooting
• Values out of range (higher/lower than expected): check sensor status, cleaning, orientation.
• Values dierent to 0 at night: water enters in the sensor, exchange the sensor.
• No values: cable cut.
8. WIND SPEED AND DIRECTION SENSOR
PI Wind Speed Sensor (IM512CD)
Maintenance
The wind sensor should be examined whether the wind wheel is low-friction. Check for easy-going and the
sound. If it is not the case, send the sensor for service to us. If the wind wheel is damaged please order a new
one.
Troubleshooting
• Heavily increment of values – replace the main board.
• Check for induction (cable rounded around the pole): cable should be positioned along the pole, but not
wrapped around it.
• Station gets frequent reset – power cable or pcb are damaged.
