parking sensors- proximity sensors for road vehicles designed to alert the driver while parking.

A hygrometer is an instrument that can range from something that is really basic in design, such as a psychrometer or the hair hygrometer, on up to more detailed
instruments, like a cooled mirror dew point hygrometer, which actually measures humidity using the condensation temperature.

analog
computers only understand digital ( only 1s and 0s and can never be anything else).Real world sensors provide analog(real word data that changes in small increments infinite possible values) signals. You need to use a converter to enable a computer to understand the analogue data. The converter works similar to a translator.
