- Page 1 PAR Light Sensor PRODUCT MANUAL Item # 3668I...
- Page 2 CONTENTS Specifications Use With a Field Scout Light Sensor Reader Use With a WatchDog Station or Logger Installation PAR Light Cosine Correction Warranty Thank you for purchasing a PAR Light Quantum Sensor to use with your WatchDog Data Logger. The sensor approximates the radiation between 400 and 700 nanometers, the most influential wavelengths for optimum plant growth.
- Page 3 Specifications Range 0-2500 µMol/m s, ±5% Excitation Voltage 3.0-5.0VDC Sensor Output 0-2.5V Linear: µMol/m s = V * 1000 Use With a Field Scout Light Sensor Reader You may wish to remove the mounting bracket when us- ing the PAR sensor with a Field Scout Light Sensor Reader.
- Page 4 Installation Use SpecWare software to program the WatchDog to log PAR Light on the desired port. Refer to the SpecWare Instruction Manual for detailed launch and/or readout instructions. PAR Light Hours and Daily Light Integral can be calculated in SpecWare Software under “Reports”. The sensor can be placed above or within plant canopies, as well as in growth rooms and greenhouses.
- Page 5 PAR Light Photosynthesis is driven primarily by photos of light with wavelengths between 400 and 700 nanometers, which is referred to as Photosynthetically Active Radiation, or PAR light. Because a quantum is the amount of energy pos- sessed by a photon, PAR light is sometimes labeled quantum light.
- Page 6 Cosine Correction Because the detected light intensity is dependent on the angle of the incoming rays, the sensor must be construct- ed to minimize this error. This is called cosine correction because the radiant intensity of the incident light is de- pendent on the cosine of the angle between the sun and an imaginary vertical line extending from the ground.
