【Features】 ● Can measure the photosynthetically active radiation (PAR) in the spectral range of 400nm~700nm. ● PAR is the energy source for plant life activities, organic matter synthesis, and yield formation. ● The sensor uses an aluminum alloy housing, which is structurally sturdy, has good sealing performance, and has a long service life. It has high-precision light sensing and good stability. ● Long transmission distance and strong anti-interference ability. ● Suitable for high-humidity and harsh environments (IP68). 【Application】 Suitable for places that require PAR measurement, such as microclimates, facility agriculture, forestry, aquaculture, solar energy, and environmental monitoring.
