HOBOnet PAR Sensor

Ein drahtloser Sensor, der die Lichtintensität für Frequenzen misst, die für die Photosynthese relevant sind; übermittelt Daten an die HOBO RX3000 oder die HOBO MicroRX Station; vorkonfiguriert und einsatzbereit.

Wichtige Informationen

Ein vollständiges System erfordert mindestens einen HOBO RX3000 Fernüberwachungsstation, a HOBOnet Drahtlos-Manager, und eine HOBOnet Drahtloser Sensor, ODER eine HOBO MicroRX-Station (mit integriertem HOBOnet Wireless Manager) und einem HOBOnet Drahtloser Sensor. HOBOnet Funk-Repeater (RX-RPTR-xxx oder RXW-RPTR-B-xxx) können hinzugefügt werden, um die Reichweite zu erhöhen.

Overview

Measures light intensity for frequencies relevant to photosynthesis. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station or pass data through other wireless sensors back to the central station. These sensors are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.
