HOBOnet PAR Sensor
Important Information
Un système complet nécessite au moins un Station de télésurveillance HOBO RX3000, a Gestionnaire sans fil HOBOnet, et un Capteur sans fil HOBOnet, OU un Station HOBO MicroRX (qui possède un gestionnaire sans fil HOBOnet intégré) et d'un Capteur sans fil HOBOnet. Répéteurs sans fil HOBOnet (RX-RPTR-xxx ou RXW-RPTR-B-xxx) peuvent être ajoutés pour étendre la portée.

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.
