£287.50

Qty:

Added Add to Cart

This sensor is a silicon-cell pyranometer. It is calibrated to measure total shortwave radiation.
The evaporation of water from soil and the transpiration of water from plant leaves are partly determined by the intensity of shortwave radiation, which is measured in Joules per meter squared per second or Watts per meter squared

Features
Output: 0 to 2.5 V (2.2 V = full sunlight 1100 W m-2)
Input Power: 2.5 to 5.5 VDC
Sensitivity: Custom calibrated to exactly 0.5 W m-2 per mV
