This paper presents a novel system for detecting concentration of the CH4 and CO gases, which exist widely in the coal industry. The system applies micro blazed grating to split the collimated light and may get the infrared absorption light with certain wavelength and bandwidth for the gases detection. The schematic diagram, calculation, signal processing, and setup were described in details. Experimental results indicate that the detection system has the ability to detect methane and carbon monoxide with maximum error of 0.169% and 58.3ppm, stability of 0.76% and 0.22%, respectively.

Quick, accurate and reliable detection of mash gas plays an important role in the coal industry. This paper presents a novel method to get the infrared absorption peak wavelength by light splitting using plane blazed grating, instead of using filter conventionally. The principle and setup of producing 3.433μm and 4.65μm wavelength lights for detecting CH4 and CO concentration are described in details. The work provides a simple, but efficient option to the infrared absorption gas detection technology.

Gas Leakage

Gas leakage is a significant problem in industries, residential premises and gas powered vehicles. Carbon Monoxide is one type of harmful gas that generates out from vehicle’s AC when it is in ON mode, which can cause suffocation or death for all the passengers within less than hour that according to the science researchers. One of the proposed methods to upgrade safety standards and prevent accidents related to gas leakage is to install gas leakage detection inside the vehicles. This paper discusses the design of gas detection system to detect the presence of a dangerous Carbon Monoxide (Co) leak inside the cars using the MQ-7 gas sensor, and an alert is provided to two users by sending SMS to the programmed mobile numbers. Also, this system decreases the gas concentration by opening the car window using a relay board and motor. If the Co (MQ-7) sensor senses any gas leakage from the AC output of this sensor goes low, and the Arduino monitors this low signal, and it will identify the gas leakage.

The increase in the number of vehicles especially cars causes the air environment to look polluted. This is caused by vehicle exhaust gases that can affect the level of human health. Harmful gases such as carbon dioxide (CO) and hydrocarbon (HC) can also enter the car cabin, making people inside feel suffocated and even death. To find out the presence of these gases, a monitoring system prototype is made which is placed in the car cabin. This system consists of input in the form of an MQ-9 sensor and a TGS2610 sensor. The readings of these sensors are processed by Arduino Uno. The system output is made in the form of a buzzer and LCD. Tests carried out on the car cabin area are divided into three, namely front, middle, and rear. The results of the 6 tests show that the smallest percentage of CO errors is 8% in the middle area and HC of 8.7% in the rear area of the car cabin.
