Campbell Scientific Aust 's Wireless Sensor Networks are made up of a CWB100 Wireless Base Station and one or more wireless sensors. The base station can be viewed as the gateway to the network. It communicates with a Campbell Scientific CR800-series, CR1000, or CR3000 datalogger via a control port.
Communication between the base station and the wireless sensors in the network is carried out using a sensor network protocol. In addition, any sensor can serve as an RF repeater to communicate with other wireless sensors. A sensor can route its transmissions through up to three other sensors on the way back to the base station.
There is a number of wireless sensors:
- The CWS900 connects to a wide variety of sensors.
- The CWS655 Wireless Water Content Reflectometer measures volumetric soil
- water content, electrical conductivity (EC), dielectric permittivity, and ambient temperature of soils.
- The CWS220 Wireless Infrared Radiometer provides a non-contact means of measuring the surface temperature of an object.
