The SQ-521 is a digital sensor with SDI-12 communication protocol. The sensor incorporates a rugged, self-cleaning sensor housing design, anodized aluminum body with acrylic diffuser, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. Typical applications include PPFD measurement over plant canopies in outdoor environments, greenhouses, and growth chambers, and reflected or under-canopy (transmitted) PPFD measurements in the same environments. Quantum sensors are also used to measure PAR/PPFD in aquatic environments, including salt water aquariums where corals are grown.

1 set consists of 6 spikes (stainless steel)

This Wind Speed Sensor is an accurate anemometer designed for applications in agriculture, meteorology, environmental monitoring, construction, infrastructure, and energy sectors. Featuring a three-cup rotor that generates electric impulses in response to wind, this sensor allows for easy integration with any datalogger or pulse meter. Wind speed is directly correlated with impulse frequency, enabling precise calculations using the formula: Wind speed (m/s) = Hz * 0.4723 + 0.2.

Remarkably sensitive, this sensor begins measuring wind at speeds as low as 0.2–0.3 m/s, thanks to its advanced ceramic bearings, which offer low friction, maintenance-free operation, corrosion resistance, and an extended lifespan. Constructed from UV-resistant ABS plastic, the sensor is lightweight and durable for long-term use. Tested and calibrated in an aerodynamic tunnel, it boasts an accuracy of ±0.2 m/s and can measure wind speeds up to 55 m/s (198 km/h), making it an ideal choice for reliable wind speed monitoring.

This Radiation Shield is designed to provide optimal protection for various air and gas sensors installed outdoors. Constructed from UV-resistant polypropylene, this durable shield features a two-part design. The upper section, in white, effectively reflects sunlight to prevent overheating, maintaining temperatures consistent with the surrounding environment. Enhanced with anti-aging additives, the plastic ensures long-lasting color and reflectance stability over time. The lower section, in black, blocks infrared radiation, safeguarding the sensitive elements inside from excessive heat and preventing inaccurate temperature readings, making it a superior choice compared to traditional all-white shields.
