The students and scientists of IISc Bengaluru have developed indigenous ventilators under “Project Prana”. Highlights The ventilator was made using pressure sensor that widely finds its application in automobile industry.Apart from the sensor, the scientists also used Reverse Osmosis Water Filters. The pressure and flow parameters in the ventilatorare controlled by using PLC board. A PLC board is a programmable Logic Controller board.It is mainly used for programming purposes. The ventilator mixes oxygen with compressed air.
