Watering of flower plant
Many times we see plants and flowers in our garden getting wilted due to lack of timely watering. Gardening has been Abdul’s hobby for long. Having noticed the problem he made a sensor controlled device that automatically switches on and off a motor depending upon the moisture content in the pot. The device is designed in such a way that when the moisture content in the soil gets below a preset value, the sensor gets activated and switches on the water pump. When the soil gets sufficiently watered, i.e. moisture goes above the preset value; the sensor switches off the motor. There are two LEDs, red and green, on the sensor box. The red coloured LED indicates water deficit whereas the green one indicates water sufficiency. He had to face considerable financial problems while developing this device and had to make and break many prototypes. The cost of the final prototype came to around Rs. 600. He has applied for patent through NIF[i]. He wants to modify the device by doing away with the motor and incorporating a magnetic system. He is still working on the concept. NIF assisted him for the development of this prototype along with a few other innovations.
