DFRobot (SEN0134) Add-On Board, Gas Sensor Module

Product Information: Accessory Type: Analog CO/Combustible Gas Sensor For Use With: Arduino Development Boards Product Range: Gravity Series Product Overview Aruino compatibe sensor board based around the MQ9 sensor, which has good sensitivity to Carbon monoxide and other combustible gases. The sensor makes detection by cycling high and low temperature; when the temperature rises (heated by 5V), it detects Methane, Propane, combustible gas etc. and cleans the other gases absorbed under low temperature. Potentiometer for sensitivity adjustment, output is proportional to the density of gas Concentration: 10-1000ppm (CO), 100-10000ppm (combustible gas) Semiconductor sensor type Requires 5V power Plug and play 3-pin Gravity interface Board size: 36.4x26.6mm Application: Embedded Design & Development, Electronics Design, IoT (Internet of Things), Hobby & Education
