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 |
