RS485 Photosynthetically Active Radiation (PAR) Sensor (400-700nm)
The RS485 PAR Sensor measures photosynthetically active radiation in the 400–700 nm wavelength range — the light spectrum that plants use for photosynthesis. It converts incident radiation into a signal proportional to light intensity, with cosine-corrected angular response for accurate readings at varying sun angles.
Built for outdoor deployment with an IP67-rated aluminium housing and a specially treated dust cover, this sensor delivers reliable measurements in harsh environments. It communicates via RS485 using the Modbus-RTU protocol and operates on a wide 5–30V DC supply, making it easy to integrate with Arduino and other platforms.
Key Features
- 400–700 nm Spectral Range – Measures the full PAR band used by plants for photosynthesis
