The Grove turbidity sensor can measure the turbidity of the water (the number of suspended particles). The optical sensor of this module can measure the density of turbid water and the concentration ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

The turbidity has been classified as a basic item to measure water quality. This research team has developed a small turbidity sensor module to measure permanent turbidity based on moving objects that ...
