The vanwaltDataNode turns any sensor into a wireless unit. It sits at location and transfers sensor measurements using radio frequency. The DataNode can accept inputs from SDI-12, MODBUS and Pulse sensors.
Inside the DataNode is a radio “tile” which enables it to communicate with a PC or a vanwaltDataGateway wirelessly over a considerable distance, up to 10 km line of sight.

The vanwaltDataNode turns any sensor into a wireless unit. It sits at location and transfers sensor measurements using radio frequency up to 10 km line of sight. If the connected sensor has memory then the vanwaltDataNode transmits the data from the sensor’s internal memory. If the sensor does not have memory then the DataNode collects the data from the sensor and stores it inside its own onboard memory.
