High-energy cosmic rays are one of the primary sources of information for\nscientists investigating the elementary properties of matter. The need to study\ncosmic rays, with energies thousands of times larger than those encountered in\nparticle accelerators, led to the development of modern detection hardware and\nexperimental methodologies. We present a low power, low complexity data\nacquisition (DAQ) system with 100 ps resolution, suitable for particle and\nradiation detection experiments. The system uses a Multiple-Time-over-Threshold\n(MToT) technique for the treatment of the output signal of Photo Multiplier\nTubes (PMTs). The use of three thresholds compensates for the slewing effects\nand offers a more accurate measurement of the PMT pulses' width. For the\nevaluation of the pulse the system uses comparators and a Time-to-Digital (TDC)\nconverter, whereas the pulses are time-stamped using the GPS signal. The\nprototype card is analyzed for its noise behavior and is tested to verify its\nperformance. The system has been designed for the HEllenic LYceum Cosmic\nObservatories Network (HELYCON) Extensive Air Showers (EAS) detector.\n
