Contact us through info@tiloom.com for a personalised quotation.

Measure the light absorption of your plant or crop and understand its needs.

Suitable for agriculture (outdoor or greenhouses), and for sports turf (golf, football, etc.) even for artificial light sources (LED, sodium or high pressure, fluorescent or halogen).


With this simple and robust instrument you can measure the light absorption (PAR or photosynthetically assimilable light) of your plant or crop.

PAR sensor detail
Front view of the PAR meter

The reading offered will be the light intensity within the optical band that can be assimilated by the plants to carry out their processes of photosynthesiswhich is between 400 and 700 nm.

Photometric spectrum PAR sensor

PAR sensor applications:

  • Outdoor crops
  • Indoor crops (greenhouses)
  • Crops with artificial light sources to promote growth (LED, High Pressure Sodium, Metal Halide, Halogen or Fluorescent).

Profits are equally valid for the agricultural industry and for the maintenance of sports turf.

Types of measurement

In favour of facilitating different options, the sensor allows to measure:

  • Concrete snapshot readings.
  • Average light intensity reading in an area.
  • Average light intensity over the course of the day (DLI, the sensor automatically takes readings for the computation of the average value, automatically and without the need for complex computers or software).

The sensor bracket allows the sensor to be placed in different positions
