Product Description

Introduction

 

The methane sensor, operating at 3.3V, utilizes TD-LAS technology with a 1653.7nm laser to identify methane by its unique absorption spectrum, unaffected by water vapor or other gas interference. Its design combines direct and wavelength modulation absorption techniques, featuring an "N" type optical path structure for extended detection sensitivity. Using a low-temperature laser and temperature compensation algorithms, it performs reliably in diverse environments. Its standard interface and protocol allow broad compatibility, making it widely applicable in methane leak detection systems in industries such as mining, catering, and industrial chemicals.

 

Feature

Applications:

a) The sensor continuously outputs the measured methane concentration, measured temperature, measured pressure, laser signal strength, laser operating temperature and fault code through the standard TTL serial port

b) It has a self-test function, which can detect whether the laser, photoelectric detector and voltage stabilization sensor are normal, which helps to eliminate the fault point.

After the sensor is powered on, it goes through a period of preprocessing (6-10s) and then begins to periodically (1Hz) output a fixed-length string. The string format is shown in the figure above.

 

Output string parsing (sample):

A 000.00 + 24.0 + 1006.22 + 16.1 + 006.0 B 00 13

A: the frame head;

+000.00: methane concentration value, two decimal places reserved, unit %vol;

+ 24.0: the environment temperature, the unit ℃;

1006.22: the environment pressure, the unit hPa;

16.1: the laser light intensity and effective range 3.6 21.6;

006.0: magnification factor, normal range 1.0-126.0;

00: fault codes

01: abnormal optical signal; 02; Ambient temperature or abnormal pressure; Optical signal is too strong; 04 laser temperature anomaly;

05: light signal is too weak;

13: xor check code

 

Fault Code

Fault code Meaning Fault code Meaning
0 Sensor working properly 3 The laser signal is strong
1 The photodetector signal is abnormal 4 Laser temperature anomaly
2 Temperature and pressure sensor abnormal 5 The laser signal is too weak

 

Precautions

a) The working voltage of the sensor is 3.3V, and the serial interface level is 3.3V;

b) sensor contains precision optical components, please avoid violent collision;

c) Working environment conditions: -40℃ ~ +70℃

d) Relative humidity 0-99% RH (non-condensation).

 

Note: The working voltage of the sensor is 3.3V. It is forbidden to connect the power supply voltage exceeding 3.6VDC to the sensor to avoid damage to the sensor.
