Abstract

A programmable wireless data acquisition system, comprising a transmitting device and a receiving device. The transmitting device is capable of receiving multiple external inputs and generating and transmitting a radio frequency signal encoded with data corresponding to the inputs. The transmitting device is variably configurable to enable it to accept inputs having different characteristics and ranges and to enable it to provide variable sampling rate, gain and filtering of the inputs. The transmitting device having a microprocessor such that the microprocessor controls the operation thereof. The receiving device is capable of receiving the radio frequency signal, demodulating it and decoding the data. The receiving device has a microprocessor such that the microprocessor controls the operation thereof. External programming device programs the transmitting device and the receiving device by wired connection or through radio frequency signal.
