As one of the leading industrial sensor suppliers, TOPOS was founded in 2003. In the beginning, it is the first company that can mass-produce the most stable glass-bead type thermistors. Ten years sharpening a sword, TOPOS becoming the high-tech company in this field. Our main products are NTC chips, NTC type thermistors (negative thermistors), Temperature sensors, Humidity/Gas sensors, widely applied in the green-car industry, smart home appliances, electronic thermometer, ... etc.

QC102 NDIR infrared carbon dioxide sensor is a common type, small size sensor ndir, using non dispersive infrared detector principle to detect the existence of CO2 NDIR in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing formaldehyde gas sensor technology, precision optical circuit design, and superior circuit design.
