Overview
A rugged weather station for outdoor environmental monitoring. Easily configurable for specific application needs, with up to 15 channels to collect environmental data and then upload it to HOBOware software for analysis. HOBOware Pro software is recommended for extended features. This station is available in two models: the U30-NRC-000-10-S100-000 and the U30-NRC-VIA-10-S100-000, which includes two analog inputs.
Features
- All electronics are housed within a rugged double-weatherproof, tamper-proof enclosure
- Setup is quick and easy with plug-and-play sensors
- Fast data offload via USB
- Optional analog inputs with sensor excitation
- Includes relay that can be activated on user-defined alarm conditions
