The SP3S-AQ2-01 series is a tin dioxide semi conductor gas sensor which has a high sensitivity to various air pollution sources (e.g. VOCs) with quick response speed.
This series uses a compact plastic housing with 3 pins configuration achieving an excellent gas sensing performance with low cost.
This model is ideal for various design of automatic air quality control systems; Ventilation Fans, air purifiers.
Gas sensitive semiconductor material is formed on the alumina substrate on which the gold electrodes are printed.
A thick film heater of ruthenium oxide is printed on the reverse of the substrate and placed in the compact plastic housing.
