สอนการใช้งานบอร์ด Arduino กับ Module sensor MQ-6 (High sensitivity to LPG)

____________________________________________________________________________

This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.

Features :

• Operating Voltage is +5V
• Can be used to detect Liquefied Petroleum Gas Sensor Liquefied Isobutane Propane Gas Module
• Analog output voltage: 0V to 5V
• Digital Output Voltage: 0V or 5V (TTL Logic)
• Dual signal output (TTL level output and analog output)
• TTL output valid signal for low level. (when the low output electric signal lights at 4. ordinary times, can be directly pick up SCM)
• Analog 0 ~ 5 v voltage, the higher the concentration, the higher the voltage.
• High sensitivity to hydrogen
• Can be resistant to ethanol steam, LPG (petroleum), smoke interference
• Has a long service life and reliable stability
• Quick response recovery feature
• Dimension (mm) : 32 (L) x 22 (W) x 27 (H) 
• เอกสารเพิ่มเติม
• MQ6 Datasheet
