Description
Description
The Seeed Studio PAR-2.5V is a photosynthetically active radiation (PAR) sensor for growers, researchers and integrators who need to log plant-usable light in the 400-700 nm band. It is part of the SenseCAP sensor family.
It outputs a 0-2.5 V voltage that maps directly to 0-2500 µmol/m²·s, so it connects to data loggers, data acquisition cards and remote acquisition modules without a protocol layer.

Frequently Asked Questions
What does the output voltage mean?
0-2.5 V corresponds to 0-2500 µmol/m²·s. Multiply the voltage by 1000 to get the PAR value.
What power supply does it need?
A 5-24 V DC supply.
Do I need to calibrate it?
No. Each sensor is calibrated before leaving the factory, and users do not need to calibrate it again.
Which wavelengths does it measure?
The 400-700 nm spectral range.
How long is the cable and how much does the sensor weigh?
The cable is 2 meters long and the device weighs 300 g.
What should I avoid when installing it?
Keep it away from chemically corrosive environments, high-voltage lines and heat sources, and do not wire it with the power on.
