Skye PAR Sensors

Solar Radiation

Skye manufacture a range of specialist light sensors and plant analysis systems. All Skye light sensors are directly traceable to NPL - Calibration Standards Body of the UK. They have a range of excellent specialised radiation sensors that measure in the specific wavelengths and with a range of outputs.

These sensors are traditionally used in plant growth studies. There are waterproof models suitable for long term exposure and underwater applications, and splashproof models of the PAR Quantum & PAR Energy suitable for glasshouses, plant growth cabinets, etc.



  • The PAR Quantum is the sensor with the ideal 100% quantum efficiency curve and is traditionally used in plant growth studies. The spectral response has been well researched and documented and is widely accepted as ‘the standard'. The PAR Quantum has an output in micromols.m-2.s-1 and the PAR Energy in watts.m-2.
  • The PAR ‘Special' has a response which has been tailored to match the light used by a typical green plant and gives an output in micromols.m-2.s-1.
  • The Energy Sensor has an output in W/m2 which can easily be matched with other sensors that output in the same units, such as pyranometers.
  • A High Output Model is also available

About the manufacturer

Skye is an employee owned company that has been manufacturing research grade systems and sensors for plant science and commercial horticulture since 1983.

The Company started on the Isle of Skye, Scotland and re-located to Wales in 1986. In addition to their standard sensors, they are able to make custom sensors for specialised applications and growth chambers.
