This paper summarizes work performed within the Polish applied research project THzOnLine aiming at multi-pixel THz detectors based on selective NMOS transistors and its application in biology, medicine and security systems. Two groups of activities were carried out in described project to develop the cost-effective solutions for the equipment dedicated to THz spectroscopy. First of them was related to optimization of design and manufacturing technology of the NMOS-based THz detectors, while the second one was dedicated to development of its readout electronics able to replace the typical expensive lock-in hardware used in laboratory experiments.
