Installation and selection
- Mount the sensing surface horizontally and keep its optical path clear.
- Use the PAR configuration when reporting photon flux density. A broadband W/m² radiation configuration measures a different quantity.
- Confirm calibration coefficient, cable, input scaling and chosen output before connecting a logger.

Frequently asked questions
What does this sensor measure for a greenhouse?
The PAR configuration measures photon flux density in the 400–700 nm band. Place it near a representative growing position to compare available plant light. A broadband radiation reading in W/m² is a different measurement.
Which output should I choose for my logger?
Choose the PAR sensor output that matches the logger input: 0–2,000 mV, two-wire 4–20 mA or RS485. Confirm the matching supply, calibration coefficient, cable and input scaling before ordering.
What should I provide when requesting a quote for the PAR Quantum Sensor?
Crop or growing environment; PAR or broadband radiation quantity; Logger input or RS485 protocol; Supply voltage, cable length and mounting
Where can I compare available model options?
Open the Weather-station equipment selection guide linked on this page. Use it to compare equipment options before requesting a configuration.
Will it work with my existing system?
Check the field signal, supply, protocol and receiving platform against the selected model. The connection options listed on this page are a starting point; send your equipment model or interface document so we can check the combination before ordering.
