RY-CGH photosynthetic radiation sensor
The photosynthetically active radiation sensor is a professional instrument used to measure photosynthetically active radiation (PAR) in the 400–700 nm band of natural light, which can reflect the level of light energy available for plant photosynthesis. This sensor uses a silicon photodetector and an optical filter to convert the incident light intensity into a voltage signal proportional to it, and can be converted into μmol/(m²·s) output. It has the characteristics of response consistent with cosine characteristics, simple structure, and can work around the clock. It is widely used in agricultural meteorological monitoring, crop growth research, greenhouse management, ecological environment research and other fields.

Introduct
RY-CGH photosynthetically active radiation sensor is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400-700nm. It is simple to use and can be directly connected to a digital voltmeter or data collector, and can be used under all-weather conditions.
Structure of photosynthetic active radiation sensor
- Optical Receiving Component: Includes a light-transmitting cover and diffuser to receive illumination from multiple directions.
- Optical Filter (400–700 nm): Precisely defines the spectral response range, allowing only photosynthetically active radiation to pass through while blocking interference from ineffective wavelengths.
- Silicon Photodetector: Converts received light signals into electrical signals proportional to radiation intensity, serving as the sensor’s core sensing unit.
- Signal Processing and Output Circuitry: Amplifies, stabilizes, and outputs weak electrical signals, supporting millivolt, voltage, or standard signals for seamless integration into data acquisition systems.
- Sensor Housing and Sealing Structure: Constructed with waterproof, dustproof, and UV-resistant materials for stable operation in outdoor and harsh environments.
- Mounting and Interface Structure: Includes mounting bases, securing threads, and cable connectors for rapid deployment in agricultural weather stations, greenhouses, or field monitoring systems.
