Introduction

Using TD-LAS technology, the 3.3V methane laser sensor detects gas through a 1653.7nm laser by absorbing methane's unique "fingerprint spectrum." It resists interference from water vapor and other gases, combining direct and wavelength modulation absorption techniques for high sensitivity. Its "N" type optical path structure allows for a longer absorption path, enhancing precision. Low-temperature laser devices and a temperature compensation algorithm ensure adaptability across different environments. Featuring a standardized interface and communication protocol, this sensor is a core element in methane detection for underground spaces, industries, and mines.

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.
