Antilog Converter Linearizes Carbon Dioxide Sensor EDN-Design Ideas 10/13/2014    Simplify gas sensor interface with some analog preprocessingWhile most carbon dioxide sensors use IR technology, electrochemical sensors are a serious competitor because of their high sensitivity, wide measurement range, and low price.  As a rule, electrochemical sensors connect to a microcontroller through a buffer amplifier with an extremely low bias current   (<1pA).  The micro is needed to linearize the logarithmic response of the sensor.__ Circuit Design by Design by Jordan Dimitrov

Catalytic Comustible Gas Sensor Combustible gas mixtures will not burn until they reach an ignition temperature.  However, in the presence of certain chemical media, the gas will start to burn or ignite at lower temperatures.  This phenomenon is known as a catalytic combustion.  Most metal oxides and their compounds have these catalytic properties___ International Sensor Technology

Low-Cost LPG Leakage Detector The circuit for an LPG leakage detector is readily available in the market, but it is extremely expensive and usually based on a microcontroller (MCU).  This project presents a low-cost circuit for an LPG detector that you can build easily.  The main objective of the circuit is to detect LPG leakage anywhere. At the heart of the circuit is dual comparator IC LM393 (IC2).  It is used to compare two different voltages, in this case reference voltage and MQ-6 gas sensor output voltage___ Electronics Projects for You

Pellistors Pellistors employ catalytic combustion to measure combustible gases or vapors in air up to the Lower Explosive Limit (LEL) * of the gas.  The standard sensor consists of a matched pair of elements, typically referred to as a detector and compensator (reference element).  The detector___ City Technology, Ltd

PIC16F84A Gas Detector using GH-312 SENSOR This is a gas detecting circuit capable of sensing many different types of gases.   The sensor used is the GH-312 and from the datasheet it is capable of sensing gases like smoke, liquefied gas, butane and propane, Methane, alcohol,hydrogen, etc. __
