GRAINSENSE USER MANUAL
1. Information for correct use
Please read this user manual carefully before using the GrainSense
solution. Incorrect use of the GrainSense device can lead to wrong
measurements of grain quality which may affect decision making.
1.1 Correct use
The following points must be observed in order to use the device in a
correct manner:
• 3.2 Requirements for reliable measurements from Operation part
(page 14)
• Adherence to the maintenance and servicing instructions from (page 20)
The device can be used during light rain. The device must never be
completely soaked or immersed in water.
1.2 Measurement errors
Observe the following points in order to avoid incorrect measurements:
• Do not take measurements when kernels are green or unripened,
GrainSense calibration does not include green colors and
measurements results cannot be assured to be accurate in such case
• Do not perform all measurements on the same plant when measuring a
component average content for the field
• Do not perform all measurements on a small area of the field when
measuring a component average content for the field
• Do not measure using an old calibration version, remember to connect
regularly the device to your phone to save data and update the latest
calibrations
• Do not measure if there is water/humidity on the tray as it will affect
moisture measurement
• Do not measure if batteries are too low, change the batteries every 50 to
150 measurements depending on battery quality and type of use
1.3 Exclusion of warranty
The manufacturer is not liable for the following damages to the device:
• Damage to the device following impacts or vibration
• Damage to the device resulting from penetrating moisture or dust
• Damage to the display resulting from pressure application and
scratches
• Malfunctions from cleaning the sample tray with cleaning agents
containing alcohol or other chemicals
• Damage caused by heat or intensive solar radiation: The device must
not be placed in the immediate vicinity of heat sources or be exposed to
direct sunlight
• Incorrect storage (see Transport and storage on page 20)

GRAINSENSE USER MANUAL
The three pillars in the GrainSense system are connected as follows:
1. GrainSense Device measures and analyzes protein, moisture,
carbohydrates and oil contents from any calibrated species and
interacts with the GrainSense Mobile application via Bluetooth.
2. The mobile application connects with cloud account and uploads
calibration and other settings to the Device and measurements
results to the database.
3. A cloud-based database and API to store the measurement
results and provide updated calibrations to the Devices (via Mobile
application). The cloud services include the GrainSense Mobile App
and the Farmer Dashboard.
2. Products
The key components of the GrainSense solution are the GrainSense
device, mobile application, and cloud-based database.

2.1 The GrainSense device
2.1.1 Mode of function
The technical principle of the device is based on near-infrared
spectroscopy by transmittance in the third overtone spectral range. This
technique has been available in labs for years, but GrainSense is the first
that has been able to incorporate it into a handheld device.
Optical method comparison
2.1.2 Scope of supply
When buying a GrainSense device, the end-user receives a package that
includes the following content:
• GrainSense device
• AA batteries (installed)
• A set of 4 GrainSense sampling spoons
• Official Cap
• Carrying case
• Quick guide
Diffuse reflection
Traditional laboratory method
- Small fraction of the sample is
measured
- Requires expensive infrared
detectors
- Long measurement time
Diffuse transmission
Advanced laboratory method
- Wet sampling not possible
- Requires large sample
- Long measurement time
- Technology complicated for
portable and affordable
devices
GrainSense
360˚ light penetration method
(integration sphere)
+ Works with simpler and
more affordable technology
+ Device can be small
+ Enables small samples
+ Wider use than grain
as other types of samples
possible
+ Short measurements time

GRAINSENSE USER MANUAL
2.1.4 Overview of the device
GrainSense device is a handheld and battery-powered device which
measures grain kernels in the field and determines protein (% dry
base), moisture (% wet base), carbohydrates (% dry base), and oil
(% dry base) contents. Those concentration units are default units for
cereals in European countries; calculation of percentages can be of any
combination of wet, dry or fixed moisture.
The device has:
• A LCD display
• A dedicated power button
- Power off by pressing the button until the display turns off
• Up and down arrow buttons to select and change view content
- If arrows are shown in the screen
• A confirmation button to move to the next phase of the
measurement process
• A Bluetooth LED to indicate a connection
- Blink: seeking connection
- Steady: connected
• A power LED to indicate battery levels
- Green: battery good
- Red: change batteries as soon as possible
Note! As batteries differ widely in performance, the LED color is a rough
indication and the user should change the batteries regularly (every 100
measurements).
