A small tip for troubleshooting with sensors

One of the best way to detect the malfunctioning of sensors is to test them with Oscilloscope . Many times sensors don't gives desired output when interfaced with micro-controller. The use of oscilloscope gives you the correct voltage response against time. This will help you to select scaling factor of Voltage to make it work for 0-5V (required for most of micro-controller). In addition to this the frequency response of voltage will enable you to select best sampling rate for your ADC.
