Product Descriptions

QS-01 is a type of tin dioxide semiconductor gas sensor, imported from Japan's FIS original air quality sensor. It has high sensitivity to various air 

pollution sources (such as VOC) and fast response time. The sensor adopts a plastic shell with three pins, which can achieve excellent sensing 

characteristics at extremely low power consumption. This product is very suitable for application in air quality control systems, exhaust fans, and 

air fresheners. Gas sensitive semiconductor materials are distributed on an aluminum substrate, where electrodes are introduced and a layer of 

ruthenium oxide is coated on the back of the substrate as a heater. They are all encapsulated in plastic shells. Reflected in the variation of 

voltage on adjustable or constant load (Rl). In order to achieve the best operating characteristics, the heater voltage (Vh), operating voltage 

(Vc), and load (Rl) must meet the standard operating conditions provided in the parameter table.
