L-PAR(1) PAR Sensor with RS485 RS232 for 400-700nm range

Photosynthetically Active Radiation (PAR sensor) in the 400-700nm range is crucial for plant growth. Our PAR sensor features a robust aluminum alloy housing, excellent sealing, high accuracy, strong stability, and anti-interference capability. Widely used in agriculture, greenhouses, aquaculture, and laboratories.

Technical Parameters

Application:

The PAR sensor is mainly used in the following areas , enabling precision light optimization for improved crop yield and energy efficiency:

1. Controlled environment agriculture: greenhouses, plant factories, and seedling nurseries for natural light monitoring, LED supplemental lighting control, DLI calculation, and photoperiod management.
2. scientific research :photosynthesis studies, light response curves,
3. ecological research:canopy light interception,
4. ornamental horticulture: succulents, orchids,
5. turf management,
6. algae cultivation in aquaculture.

FAQ of PAR Sensor:

1. Can the sensor measure LED lighting?
   Yes. PAR sensors measure all light within the 400-700nm spectrum, accurately detecting natural sunlight, LED, and HPS lamps.
2. Can the cable be extended?
   Yes. Please specify your required cable length in advance.
3. Why do PPFD values vary significantly across locations?
   This is normal. Light is usually weaker at edges and corners and stronger in the center due to obstructions. Install sensors at representative positions for accurate data.
4. What is the difference between PAR and Lux?
   PAR measures photosynthetically active radiation (400-700nm, μmol/m²/s), Lux measures human-visible illuminance (lm/m²). PAR is a more scientifically accurate indicator of plant light requirements.
