HOBOnet Temp/RH Sensor

Alimentazione solare

Un sensore wireless a energia solare che funziona con il sistema HOBOnet per monitorare la temperatura dell'aria e l'umidità relativa.

Informazioni importanti

Un sistema completo richiede almeno un Stazione di monitoraggio remoto HOBO RX3000, a HOBOnet Wireless Manager, e un Sensore wireless HOBOnet, OPPURE uno Stazione HOBO MicroRX (che dispone di un Wireless Manager HOBOnet integrato) e di una Sensore wireless HOBOnet. Ripetitori wireless HOBOnet (RXW-RPTR-xxx o RXW-RPTR-B-xxx) possono essere aggiunti per estendere la portata.

Overview

A solar-powered wireless sensor that works with the HOBOnet system to monitor air temperature and relative humidity. 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.
