Explosive Gas Detector Circuit
A gas sensor (TGS823 from Allegro Electronics, Cornwall Bridge, CT 06754) conducts in the presence of explosive gases. U5 is a voltage-to-frequency converter that produces a frequency proportional to the sensor conductance. The output frequency ranges from 100 Hz in...
The application circuit diagram of thermal conductivity gas sensor with RTD
The sensor operates on the principle that at high temperatures (200 to 800 °F), the temperature of the sensor varies with the thermal conductivity of gas, leading to changes in the resistance of the platinum resistor wire. In the circuit,...
gas leakage alarm
LPG gas is supplied in pressurized steel cylinders. Being heavier than air, it tends to flow along the floor and settle in low spots such as basements when leaked. This poses risks of fire or suffocation if not addressed. A...
Triac gas - smoke alarm circuit schematic
In the presence of combustible gas, the conductance of the TGS308 gas sensor increases, causing the voltage at the potentiometer RP1 slide point to rise from a normal 3V RMS to 20V. This elevated voltage is applied to transistor VT1...

Gas Leakage Sensor Alarm Circuit Engineering Project using 555 Timer and MQ6 SEN 1327 Gas Sensor Module
This article discusses a home security alarm circuit designed to detect LPG gas leakage. The circuit utilizes a gas sensor module, SEN 1327, which incorporates a QM 6 gas sensor. The output signal from this gas sensor module is used...
Detecting liquified petroleum gas (LPG)
Figaro manufactures sensors that can detect various types of gases (e.g., hydrogen, methane, carbon monoxide, etc.). A simple circuit has been designed around the Figaro LPM2610 module, which will activate an alarm if the level of liquefied petroleum gas (LPG)...
Alcohol used to monitor gas concentration gas sensor circuit diagram
Ceramic gas sensors can be utilized to analyze the content of alcohol vapor. With the appropriate sensor circuit, it is possible to detect blood alcohol content. The operating principle is straightforward: if blood alcohol content is present in a certain...
