Pratyush Bansal and Aekas Singh Gulati who study in the eighth grade of Global Indian International School (GIIS) Indian-origin students in Singapore have developed a device which enables automated watering of plants, ensuring the plants don't suffer while you are away at work or vacations. The device consist of a moisture sensor with hygrometer detector.
According to Bansal and Gulati, "We have used a moisture sensor with hygrometer detector which has been connected to a two litres water tank and a water pump motor. A battery and a liquid crystal display completes the functioning…So when the water tank is filled and the connecting pipe left in the pot, the moisture sensor detects when the water is needed and the motor pumps water from the tank which will have to be filled every two weeks. If there are multiple pots as many number of pipes can be connected to the device”.
The duo was also selected to display their device at the Young Innovators Programme at IIT Kharagpur. The students who are working on commercial viability of the device have estimated its cost at 9 Singapore dollars (Rs 470).
According to the young researchers, “We are now trying to add a wifi enabled circuit board to it with GSM module which will automatically link our mobile phones to the device and we can monitor watering of our plants using an app".
