TGS813 Semiconductor Gas Sensor For Domestic Gas Leak Detection
Portable Gas Detection
- Product Usage:
- Domestic Gas Leak Detection: It is suitable for being used in
domestic gas leak detectors and alarms. Due to its high sensitivity
to methane, propane and butane, it can effectively detect the
leakage of natural gas, liquefied petroleum gas (LPG) and other
combustible gases in the home, providing safety protection for
family life.
- Portable Gas Detection: Can be applied to portable gas detectors,
which is convenient for users to carry and detect the concentration
of combustible gases in different environments, such as in
industrial sites, construction sites or some areas where gas
leakage may occur.
- Industrial Combustible Gas Alarm: Used in industrial - grade
combustible gas alarms, which can monitor the combustible gas
concentration in industrial production processes, and give an alarm
in time when the gas concentration exceeds the standard, to prevent
the occurrence of safety accidents such as explosions and fires.
- Product Features:
- Wide - range Sensitivity: It is a general - purpose gas sensor,
which is sensitive to a wide range of combustible gases, including
methane, propane, butane, etc., and has good detection performance
for different types of combustible gases.
- High Sensitivity: It has high sensitivity to methane, propane and
butane. It can quickly and accurately detect the existence of these
gases, and can still maintain good sensitivity even at low gas
concentrations, which is very important for early warning of gas
leakage.
- Long Service Life: With the advantages of long - term stable work,
it can maintain reliable detection performance within a long - time
use, reducing the frequency of sensor replacement and reducing the
use cost and maintenance workload.
- Low Cost: The production cost is relatively low, which makes it
have a great advantage in price when applied to various gas
detection occasions, and is conducive to wide - range promotion and
application.
- Simple Circuit Requirements: It can work with a simple circuit.
Users can convert the change of sensor conductivity into an output
signal corresponding to the gas concentration through a simple
circuit design, which is convenient for circuit design and product
development, and also helps to reduce the overall cost of the
product.
