LoRaWAN Ambient Light / PAR Sensor Kit
Model: PS-420
A LoRaWAN PAR sensor measures photosynthetically active radiation for greenhouses, vertical farms, and canopy monitoring. The PS-420 reports PAR and ambient light levels over LoRaWAN so crop software can correlate growth stages with supplemental lighting decisions. Greenhouse operators use PS-420 to verify supplemental lighting output at canopy height and to compare shade-cloth trials season over season. PAR and lux channels decode separately so horticulture software can chart photosynthetic input alongside facility lighting maintenance alerts. Suitable for OEM greenhouse automation programmes.

What is a LoRaWAN PAR sensor?
PAR quantifies light wavelengths plants use for photosynthesis (roughly 400–700 nm). PS-420 suits greenhouse glazing transmission checks, supplemental HPS/LED scheduling, and shade-cloth trials. Ambient lux channels help facility teams spot failed lamps before crop stress appears. Install at canopy height with documented orientation for repeatable season-over-season comparisons.
Mount at canopy height with consistent orientation between seasons so PAR comparisons remain meaningful. Supplemental lighting trials should log both PAR and lux — lux helps spot failed lamps while PAR tracks photosynthetic input. Clean the diffuser on greenhouse units when algae or dust accumulates on the glazing seasonally. Vertical farms often deploy one sensor per tier during commissioning, then standardise on representative rows once light uniformity is verified across the rack.

Decoder & Integration
PAR (µmol/m²/s), lux, battery, and device temperature are encoded in PS-420 uplinks. Use the decoder profile to feed horticulture SCADA or cloud agronomy platforms. PAR and lux fields align with common horticulture SCADA tags. Set reporting intervals to match crop stage — faster during lighting commissioning, slower during stable growth periods to preserve battery. Factory functional-test records and TTN/ChirpStack decoder maps ship with every kit. Map uplink bytes once on your network server, then reuse the profile across sites.
