Smart Water wireless sensor platform simplifies remote water quality monitoring. Equipped with multiple sensors that measure a dozen of the most relevant water quality parameters, Waspmote Smart Water quality-sensing platform features autonomous nodes that connect to the Cloud for real-time water control. Waspmote Smart Water is suitable for potable water monitoring, chemical leakage detection in rivers, remote measurement of swimming pools and spas, and levels of seawater pollution.
The water quality parameters measured include:
dissolved oxygen (DO)
oxidation-reduction potential (ORP)
dissolved ions (Na+, Ca+, F-, Cl, Br-, I-, Cu2+, K+, Mg2+, NO3-)
New turbidity sensor
Turbidity is the haziness of a fluid caused by individual solid particles that are generally invisible to the naked eye.
The measurement of turbidity is a key test of water quality. Nephelometers, or nephelometric turbidimeters, measure the light scattered at an angle of 90° by one detector from the incident light beam generated by an incandescent light bulb. Readings are reported in Nephelometric Turbidity Units (NTU).
The measurement of turbidity is important in the following scenarios:
Urban waste water treatment (inlet |outlet controls)
Industrial effluent treatment
Surface water monitoring
The turbidity sensor probe has a range from 0 to 4000 NTU (0-4500mg/l), and allows to detect if the measured water is potable (< 1 NTU) or not, as it has an accuracy of 1 NTU. The sensor probe comes calibrated from factory although periodic calibration is required to maintain the maximum accuracy; to do so Libelium provides calibration kits.
