Product Description

Apogee Red - Far-Red sensors combine two photodetectors designed to measure wavelength ranges and peaks that approximate phytochrome absorption. The red / far-red ratio can be calculated from these measurements. Red and far-red wavelengths are of particular interest because they influence photosynthetic and morphogenic activity. Phytochrome pigments sensitive to varying ratios of red and far-red light provide information to the plant about its light environment.

Accurate Red:Far-Red Measurement

Designed specifically for agricultural and horticultural applications, the S2-131 utilizes a differential spectral measurement technique to accurately detect the ratio of red (660 nm) to far-red (730 nm) light. This enables vital analysis of plant light environments, supporting growth optimization and research.

Rugged, Weatherproof Design

Manufactured with a white ABS/polycarbonate enclosure, the sensor boasts IP65-rated weatherproofing, making it suitable for both indoor and outdoor use. Its compact and durable build ensures consistent performance in demanding conditions such as greenhouses, plant canopies, and growth chambers.

Easy Installation and Integration

The S2-131 comes ready with a 2-meter cable and gold-plated 3-pin connector for straightforward panel or bracket mounting. It is compatible with common dataloggers and control systems, allowing for seamless integration into existing monitoring setups.

FAQ's of RED - FAR-RED SENSORS (S2-131):

Q: How is the RED - FAR-RED SENSOR (S2-131) calibrated and maintained?

A: The sensor is factory calibrated for accuracy, though periodic recalibration is recommended to maintain optimal performance. Maintenance is minimal and involves cleaning the sensor window periodically to ensure accurate light detection.

Q: What environments can the S2-131 sensor be used in?

A: The S2-131 is designed for use in agricultural, horticultural, and research environments such as plant canopies, greenhouses, and growth chambers. Its IP65 weatherproof rating and wide temperature range (-10C to +60C) allow reliable operation in diverse environmental conditions.

Q: When should I consider recalibrating the sensor?

A: Recalibration should be performed periodically, especially if the sensor is used in demanding or variable environments. This helps maintain its superior accuracy of 2% in long-term applications.

Q: Where can the sensor be mounted and how is it installed?

A: The sensor supports panel or bracket mounting, making it versatile for placement above plant canopies or within controlled environments. Simply connect it using the provided 2-meter cable and 3-pin gold-plated connector for easy integration.

Q: What are the primary benefits of using the S2-131 for plant growth monitoring?

A: By accurately measuring the ratio of red to far-red light, the sensor provides essential data for optimizing plant growth conditions, allowing informed decisions in agricultural and horticultural management. It also features high sensitivity, quick response, and compatibility with standard data collection systems.

Q: How does the S2-131 interact with other control systems or dataloggers?

A: The analog output signal from the sensor is compatible with most commercially available dataloggers and control systems, making data acquisition and monitoring straightforward. Integration is facilitated through a standard 3-pin interface and 2-meter cable.

Q: What process does the sensor use to measure light ratios?

A: Employing a silicon photodiode array, the S2-131 uses differential spectral measurement to separately detect red (600-700 nm) and far-red (700-800 nm) light, providing a highly accurate R:FR ratio for research and agricultural applications.
