This is a wireless sensor that measures water level using radar technology. The combination of a high-tech radar level
sensor combined with a wireless sensor using Texas Instrument's advanced Sub-GHz technology enables long-range
transmission with extremely low energy consumption. It will connect 2-way wireless with WS433-CL wireless co-
ordinator to send data and receive configuration. It can be configured with operational parameters such as data
delivery interval, health check cycles ... remotely from the Globiots platform or via the ModbusRTU software (via
WS433-CL). Its default data rate is 50 kbps, which can be converted to 625 bps for increased communication range.
The sensor can operate for up to 10 years with just one AA battery. Sensors can be used to measure water or liquid
levels as well as for measurement in areas such as river level monitoring, chemicals, municipal water supply and
drainage, etc.
