Description for pins Communication Protocol 1. General Settings Table 3 Baud Rate 9600 Data Byte 8 bits Stop Byte 1 bits Check Byte Null 2. Communication Commands There are two kinds of communication, initiative upload mode and question & answer mode. Default settings is initiative upload mode. Modules upload gas concentration value every other 1S, Note: The modul e will automatically switch to Q&A mode (question & answer mode) after an inquiry command is received; The module will automatically switch to initiative upload mode if no inquiry command is received within 30 seconds under Q&A mode. command line format as follow: Table 4 Byte0 Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8 Start Byte Gas Name Unit ppm No. of decimal Concentration (High Byte) Concentration (Low Byte) Full Range (High Byte) Full Range (Low Byte) Check sum 0xFF 0x01 0x03 0x00 0x00 0x00 0x30 0xD4 0xF8 Pin No. Description Fig2.Module pin Pin1 Vin Pin2 GND Pin3 Relay control, active High 1)Normal work status: low level for long 2)Alarm status: high level for long Pin4 UART(RXD) data receiver Pin5 UART(TXD) data transmitter(including defect information) Pin6 Solenoid valve control, active High 1)Normal work status: low level for long 2)Alarm status: pulse signal of high level for 500ms, low level for 500ms Pin7 Buzzer control, active High 1)Malfunction status: high level for 100ms, low level for 900ms 2)Alarm status: pulse signal of high level for 500ms, low level for 500ms Pin8 Preheating within 3 minutes: high level and low level in turn for 1s once; 1) Normal work status: high level for long 2) Malfunction status: low level for long.

Gas name: 0x01 is for CH4. Concentration (High Byte): The highest bit(bit 8) is for sensor fault judgment; Note: sensor fault judgment: 1 is for sensor failure, 0 is for no failure. Gas concentration value = The low 5 bit of High Byte*256+Low Byte. Full range= full range (high byte)*256+ full range(low byte) (0X30D4=12500ppm, which means the module range is 12500ppm) To read gas concentration, command line format as follow: Stable5.

Installation instruction This module connects with external part by adopting Pin1.25mm*8 single-row inserting pin, there are four holes with 2mm diameters at the four corners, users fix the module through locations holes and make connection through Pin1.25mm*8 wire. Cautions 1 .Following conditions must be prohibited
1.1 Exposed to organic silicon steam
Sensing material will lose sensitivity and never recover if the sensor absorbs organic silicon steam. Sensors must avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment.
1.2 High Corrosive gas
If the sensors are exposed to high concentration corrosive gas (such as H 2S, SOX, Cl2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation.
1.3 Touch water
Sensitivity of the sensors will be reduced when spattered or dipped in water.
1.4 Freezing
Do avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity. 2 . Following conditions must be avoided
2.1 Water Condensation
Indoor conditions, slight water condensation will influence sensors’ performance lightly. However, if water condensation on sensors surface and keep a certain period, sensors’ sensitive will be decreased.
2.2 Used in high gas concentration
No matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensors characteristic will be affected. If lighter gas sprays the sensor, it will cause extremely damage.
2.3 Long time storage
The sensors resistance will drift reversibly if it’s stored for long time without electrify, this drift is related with storage conditions. Sensors should be stored in airproof bag without volatile silicon compound. For the sensors with long time storage but no electrify, they need long galvanical a ging time for stability before using. The suggested aging time as follow: Stable9. Storage Time Suggested aging time Less than one month No less than 48 hours 1 ~ 6 months No less than 72 hours More than six months No less than 168 hours
2.4 Long time exposed to adverse environment

No matter the sensors electrified or not, if exposed to adverse environment for long time, such as high humidity, high temperature, or high pollution etc., it will influence the sensors’ performance badly. 3. Please make sure the three anti -paint on the control board is completely dry before the module is installed. 4. Please do not plug the module under power-on condition.
