Arduino Compatible Smoke/Gas Sensor Module

Description Show Reviews This is a smoke and gas sensor on a small circuit board that is designed to work with all of the Arduino boards. It is easy to incorporate into any project requiring only a 5v supply, ground, and an analog input to measure the sensors readings. It can be used to detect any number of gasses or smoke and would be ideal for use in homes where gas build-up can occur (for example in garages with welders) or on search and rescue robots. Key Features: Includes the sensor and connector cable Main chip: LM393, ZYMQ-2 gas sensor Trim pot on the sensor board to calibrate sensor sensitivity Working voltage: DC 5V With LED signal output indicator Dual signal output: AO output & TTL level TTL output effective signal: low level (the LED light on, can connect to the microcontroller directly) 0~5V analog output voltage, the higher the concentration the higher the voltage Quick response, long life and reliable stability High sensitivity to liquid gas, natural gas, coal gas, etc. 2 Mounting holes on the PCB Dimensions: Depth 17.7mm, Height 42.9mm, Width 21.5mm, Weight 9.2g Sensor Data Sheet: http://www.seeedstudio.com/depot/datasheet/MQ-2.pdf 0 Reviews Hide Reviews Show Reviews
