Get the pulse of your data with HOBOnet!

The HOBOnet Wireless Pulse Input Sensor connects to sensors with pulse output. This sensor is compatible with contact closures, such as tipping-bucket rain gauges or reed switches. HOBOnet Wireless Sensors communicate data directly to the HOBO RX3000 weather 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 the LI-COR Cloud IoT platform (formerly HOBOlink).

This sensor measures pulses and is designed to work with the HOBOnet® (HOBO® RX) Wireless Sensor Network in which data is transmitted wirelessly from the sensor mote across the network to the station and then uploaded to the LI-COR’s Cloud IoT platform. With the LI-COR’s Cloud IoT platform, you can monitor sensor readings, view graphs, set up alarms, download data, and more.

Important Information

Compatible with contact closures, such as tipping-bucket rain gauges or reed switches. A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor, OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.
