Deploy quickly and easily with preconfigured settings

The HOBOnet Wireless Pulse Input Sensor connects to sensors with a pulse output. This sensor is compatible with electronic switch closures, such as FET or open-collector outputs, or CMOS-level logic signals. 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 HOBOlink, Onset’s innovative cloud-based software platform.

Important Information

Compatible with electronic switch closures, such as FET or open-collector outputs, or CMOS-level logic signals. 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.

• For maximum battery life, the pulse input sensors should be used with their preferred switch type. The sensors will
work with active high inputs (RXW-UCC-xxx) and normally closed switches (RXW-UCD-xxx), but battery life will not be
optimized.

Onset have a complete range of HOBOnet wireless sensors and external Smart Sensors to suit the HOBO RX3000, RX2100 Range, U30, H21 and H22 Data Logger series.
