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.
Wirelessly transmits real-time temperature and 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.
