One FieldMate can give enough information about 1 crop in an homogeneous area of 3-5km (without mountains, rivers or other factors that can change the meteorological conditions).

• Precipiation

          Accuracy of 5%

• Temperature at crop and field height

          Accuracy of 0.5 °C (in range from -10 °C to +85 °C)

• Relative humidity at crop and field height

          Accuracy of 2% (in range from 0-100%)

• Soil temperature (-5cm & -20cm) 

          Accuracy of 0.5 °C (in range from -10 °C to +85 °C)

After installation, it can take a while for data to come in. Please give FieldMate at least 1 hour to collect and send data after installation.

If you do not receive any data after one hour, please check the following:
– Is the FieldMate connected to the app?
– Is the FieldMate ‘on’? Check if the grey head is ‘stuck’ to the white technology pole

All answered with yes, but no data yet?
Probably the range at the current location is too poor to send data.
– Unscrew the grey head from the white technology pole and move the FieldMate to another location.
– Screw the 2 parts back together and wait for data to come in. If data comes in, change the location of the FieldMate to the new location in the sensor settings.

If you have several FieldMates, it is recommended to place the FieldMate without data next to an already working FieldMate to ensure the availability of connectivity.

The FieldMate sends data every half an hour between 06:00AM and 10:00PM. Between 10:00PM and 06:00AM data is measured every 15 minutes as usual. At 06:00 all night data will be send at once.

Before relocating the FieldMate to another location, turn the grey head with rain gauge off the white technology pole.
Take both parts with you to the new location. Dig/drill a hole of 25cm. Place the white technology pole in the hole and press the ground so that the pole is firmly in place. Click and turn the grey head with rain gauge on the pole, so that the FieldMate turns ‘on’.

Then change the location of the FieldMate in the SmartFarm app.
Open the relocated FieldMate in the app and click on the settings icon in the top right corner. At the bottom of the sensor settings you will see the location of the FieldMate. Click on the pointer to change the location to the new one. Then click on save.

Because of its unique design, the FieldMate requires very little maintenance. However, it is advisable to check the FieldMate for maintenance once in a while or in the event of any deviations.
The spoon of the rain gauge should be checked for dirt. Remove any sand, dust or other debris. Check the sun shields for spider webs or other debris that could affect the measurements.

To compare the values of a manual rain glass with those of the FieldMate, you should take into account the following things:
– The rain glass must be certified for rainfall measurements with minimal deviation
– The rain glass must be directly next to and at the same height as the FieldMate
– Measurements should be compared in the same time range. The FieldMate measures from 00:00 to 23:59, whereas we are used to looking at the rain glass in the morning after breakfast
– When recording the amount of precipitation in the rain glass, take note of the lower ‘line’ in the glass. When you look straight at the glass, you will see 2 ‘lines’ in the water. This has to do with surface tension. Because of the tension, the water creeps up along the glass, which gives a disturbed image. The bottom line is the true amount of precipitation.
– Do you have half a mm too much or too little? The spoon in the rain gauge measures 0.5mm at a time. When the spoon contains 5g, the spoon falls over. If it contains 0.48g, the spoon will not be emptied until the next shower contains 0.2g. This also means that you will not see rainfall in the app immediately when it has just started raining.

Yes, you can! Because the FieldMate is modular, you can replace the battery. Please contact our support team to order a new grey head with rain gauge.
