The device has been developed as per as the requirements of the Department of Biomedical Physics & Technology , University of Dhaka, Bangladesh, for one of their postdoctoral students project of Solar Water Filter. It is used to measure humidity and temperature from two channels where the sensors are connected. There is a push button to select the channels. The manufacturing cost of the device is about 30 USD.
