HOBOnet Wireless Temperature Sensor

Ein solarbetriebener drahtloser Sensor, der mit dem HOBOnet-System arbeitet, um Luft-, Boden- und Wassertemperaturen zu überwachen.

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 (RXW-RPTR-xxx oder RXW-RPTR-B-xxx) können hinzugefügt werden, um die Reichweite zu erhöhen.

Overview

A cost-effective and scalable solution for web-enabled monitoring of air, soil, and water temperatures. 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. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.
