Da Data Acquisition on The process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. • Data acquisition system , also known as DAS or DAQ , is a system that performs the above process Physical Transducer Signal Analog - Digital Computer Converter System Sensor Conditioning 8 Bit Code 2 2 2 2 Physical System Noisy Signal Filtered Signal Digitalized Signal 0 1 1 1 1.5 1.5 1.5 1.5 0 0 0 1 1 1 1 1 0 1 1 1 Measured Value Measured Value Measured Value Discrete Value 1 0 1 1 0.5 0.5 0.5 0.5 1 1 0 0 0 0 0 0 1 1 1 1 -0.5 0 1 1 0 -0.5 -0.5 -0.5 1 0 1 0 -1 -1 -1 -1 1 1 1 0 1 1 1 1 -1.5 -1.5 -1.5 -1.5 0 1 1 1 -2 -2 -2 -2 0 5 10 15 20 25 30 1 1 1 0 0 1 2 3 4 5 6 7 8 9 10 0 1 2 3 4 5 6 7 8 9 10 0 1 2 3 4 5 6 7 8 9 10 Sample Number Seconds Seconds Seconds 1 1 1 1 0 0 1 1 Physical Signal Noisy Electrical Signal Conditioned Signal 2 1 1 0 0 Digitalized Signal 0 1 1 1 1.5 0 1 1 1 1 0 1 1 0 Discrete Value 0 1 1 0 0.5 1 0 1 1 0 1 1 1 0 0 0 0 1 -0.5 1 1 1 1 -1 1 0 1 1 0 0 1 0 -1.5 0 0 1 1 -2 1 1 1 1 0 5 10 15 20 25 30 Sample Number 1 0 0 1 1 1 0 1 Digitalized Signal 1 1 1 0 https://en.wikipedia.org/wiki/Data_acquisition 3

Re Remote Data Acquisition • Traditional, wired sensors Network sensor field Remote monitoring Data loggers Local monitoring 4

Re Remote Data Acquisition • Wireless sensors • Sensors communicate with data logger via radio links Network sensor field Remote monitoring radio link 5

Re Remote Data Acquisition • W ireless S ensor N etworks – WSN • Sensor nodes deployed and forming an ad hoc network ◦ Requires no hubs, access points ◦ Instantly deployable Sensor node Sensor network Network Gateway • Targeted applications ◦ Emergency responses ◦ Hazardous area monitor Remote monitoring 6
