For the effective use of groundwater, proper monitoring is essential. The method used to indicate the water level in borewells before this innovation was rather primitive: a special tape with chalk marks was inserted into the well but the measurement lacked accuracy. The basic idea was to produce an indication which is visible or audible when a particular material touches the water. The innovator developed a device that produces a beep sound and a visual indicator glows when a probe touches the water. The probe is attached to a 50 m long graduated and insulated wire which is fixed on a wheel. This wheel is connected to a stand and can rotate on the axle. One end of the wire is connected to the circuit (PCBs, IC, battery, transistors, and resistances) that is fixed at the hole in the centre of the wheel. The wire is inserted into the borewell and when the tip of the probe touches the water, the LED glows and a beep sound is heard, indicating the water level in the graduated wire. |
