LPG Gas Sensor Interfacing with LPC2148 ⋆ EmbeTronicX

Working with Gas Sensor. Using an MQ sensor it detects a gas is very easy. You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas is detected the output LED will remain turned off meaning the digital output pin will be 0V (LOW). Remember that these sensors …
