PAR Sensor
A PAR sensor in a waterproof aluminum enclosure with a 1.5m cable. The sensor comes pre-calibrated and doesn`t require any subsequent calibration. The base comes with a small tripod, mounting bracket, and bubble level. The board uses the Qwiic Connect System, an easy-to-use, polarized, push-to-fit connector. No more mistaken connections or soldering header pins. Adafruit calls these connectors STEMMA QT.
Measure Photosynthetically Active Radiation
- 400~700nm spectral range
- ±5% accuracy
