A sensor network system is being used for mapping and monitoring the water quality of river Yamuna.

The Yamuna was considered a nurturing and life-enhancing goddess in the past. Legend has it that bathing in the sacred waters of the Yamuna, the sister of Yama, the god of death, frees one from the ordeal of death. The 1376-km river is a tributary of the Ganga and originates in the Yamunotri glacier in the lower Himalayas. It passes through several states in north India including Uttarakhand, Haryana, Uttar Pradesh and Delhi where the river was once its lifeline.
