Contoh Penggunaan Dasar Sensor Gas TGS2602 dgn Microcontroller AVR Atmega8535


Sensor Figaro TGS 2602 :
The Figaro 2600 series is a new type thick film metal oxide  semiconductor, screen printed gas sensor which offers
miniaturization and lower power consumption. The TGS 2602 has high sensitivity not only to air contaminants which are emitted
by cigarette smoke, but also to low concentrations of odorous gases such as ammonia and H2S generated from waste materials
in office and home environments.
