In the present work, a tin oxide (SnO₂)-based gas sensor has been fabricated on Low Temperature Co-fired Ceramic (LTCC) substrate by screen printing method for detection of the silent killer gas (carbon monoxide). The tin oxide paste has been prepared for deposition on inter-digitated electrodes patterned on LTCC substrate. The developed gas sensor module has been fired at different temperatures (625, 820 and 860°C) and the effect of firing temperature has been studied. The developed sensor is small in size with low power consumption, better sensitivity and repeatability.
