RS485 Photosynthetically Active Radiation (PAR) Sensor (400-700nm)
22 units will be available shortly.
Introduction
The RS485 Photosynthetically Active Radiation (PAR) Sensor measures the light spectrum essential for plant photosynthesis (400-700nm). By converting sunlight into a voltage signal proportional to radiation intensity, it ensures accurate monitoring of light available for plant growth. Its high-precision design includes a cosine corrector for reliable measurements at varying light angles. The sensor features a specially treated dust cover to minimize environmental interference and supports RS485 Modbus-RTU communication. Operating on a wide DC voltage range (5-30V), it integrates seamlessly with platforms like Arduino.
Wide Voltage Range and Easy Integration
With a DC 5-30V power supply, the sensor is compatible with a variety of systems. Its RS485 Modbus-RTU protocol allows straightforward connectivity with microcontrollers like Arduino, enabling efficient data collection.
High Precision and Reliability
Equipped with high-precision photoelectric elements, the sensor accurately measures PAR within the 400-700nm spectrum. The built-in cosine corrector ensures precise response to different light angles, making it ideal for environmental monitoring.
Durable and Weather-Resistant
Housed in a metal aluminum shell with an IP67 rating, the sensor is resistant to dust, water, and harsh weather conditions. The specialized dust cover enhances long-term stability by reducing environmental contamination.
