GreenSeeker Handheld Crop Sensor

The Trimble GreenSeeker handheld crop sensor is an affordable, easy-to-use measurement device to assess the health — or vigor — of a crop in order to make better nutrient management decisions on your farm.

Use the GreenSeeker handheld to instantly take a reading of your crop’s health. Readings can be used to make non-subjective decisions regarding the amount of fertilizer to be applied to your crop, resulting in more efficient use of fertilizer — a benefit to your bottom line and the environment.

New Bluetooth® connectivity now allows data collection with the mobile devices you already own. Simply download the app of your choice and connect your phone or tablet to the sensor via Bluetooth to record and save data for future analysis. (Recommended apps linked below.)

How to Use

  • The sensor emits brief bursts of red and infrared light and then measures the amount of each type of light that is reflected back from the plant
  • The sensor continues to sample the scanned area as long as the trigger remains engaged
  • The sensor displays the measured value in terms of an NDVI reading (ranging from 0.00 to 0.99) on its LCD display screen
  • The strength of the detected light is a direct indicator of the health of the crop; the higher the reading, the healthier the plant
