Watchport® Sensors for Drop-in Networking

• Monitor critical environmental data such as temperature, humidity, distance, acceleration, moisture
• Plug into XBee® sensor adapter for easy wireless connectivity*
• Monitor over a WAN connection using ConnectPort™ X gateway
• No external power supply needed
• Product datasheet

Watchport sensors provide a plug-and-play solution for Drop-in Networking applications. Each sensor connects to Digi's XBee sensor adapter (sold separately) for wireless connectivity to sensor data over a low power ZigBee® network.

When used in a Drop-in Network with Digi's ConnectPort X gateways, Watchport sensors can be monitored over a Wide Area Network (WAN) connection, providing centralized monitoring of geographically distributed sensor points. Plus, the Python® programming engine on the ConnectPort X provides the software tools to integrate multiple sensors and create custom applications using sensor readings.

*Sensors must be used with XBee sensor adapters for wireless monitoring of sensor data in Drop-in Networking applications.
