solar radiation sensor

PYR pyranometer


A sensor the measurement of global solar radiation between the wavelengths of 380 nm and 1120 nm. The PYR sensor is ideal for a portable, handheld measurement or for continuous measurements with a data logger.

The PYR global solar radiation sensor is ideal for growers, students and scientific researchers.


  • Low cost, high accuracy sensor
  • Voltage output to connect to our data loggers or your existing data loggers
  • Mounting plate with spirit level for accurate installations


handheld or continuous measurement options

Handheld PAR MeterEdaphic Scientific can supply the PYR solar radiation sensor with either a handheld, portable meter or we can connect the sensor to a data logger for continuous measurements.

The PYR easily connects into the Procheck Handheld Meter for a portable measurement option. Simply insert the stereo plug into the Procheck and measurements will be displayed on the LCD screen. The Procheck can support additional sensors and parameters including soil moisture, water potential, temperature, relative humidity, and solar radiation.

For continuous measurement, the PYR solar radiation sensor supported by the Em50 Data Logger or Em50G Wireless Data Logger. The PYR sensor connects directly into the Em50 or Em50G and is pre-programmed and ready to measure.


weather station options

Weather StationFor optimal measurements, the PYR solar radiation sensor can be connected to our range of weather stations.

The PYR solar radiation sensor provides valuable measurements on the light environment. However, this information can be incomplete because it does not include other important variables for plant growth including rainfall, temperature, relative humidity, vapour pressure deficit (VPD) and wind speed and direction. By connecting the PYR solar radiation sensor to a weather station system, complete knowledge of the plant growth environment can be obtained.
