HOBO ZW-003 Temperature/Relative Humidity (RH) Data Node
The HOBO® ZW-003 is a two-channel wireless data node with an integrated temperature and relative humidity sensor. It wirelessly transmits data in real time, reducing the costs and inconvenience associated with manual data offload.
Features:
- Wirelessly transmits real-time temp & relative humidity data
- Compact size for easy deployment wherever data is needed
- Notifies you of alarm conditions via email or text messages
- Onboard buffer memory helps prevent data loss
- Powerful HOBOware® Pro software for organizing and viewing data (included with HOBO data receiver)
A complete system requires at least one wireless HOBO data node, HOBO data receiver (ZW-RCVR), and HOBOware Pro software (included with ZW-RCVR). Depending on your system deployment, a HOBO data router (ZW-ROUTER) may be required.
