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.
