Dimension
Wiring connection
The air carbon dioxide sensor can be connected to various data collectors and data acquisition cards carrying differential inputs, the wiring diagram for remote data collection modules and other equipment is shown in the following figure:
Attention
Be careful when wiring. If the power supply voltage is too high or the polarity is reversed, it will cause permanent damage to the sensor.
Basic communication parameters
RS485 signal, standard Modbus RTU protocol
Baud rate: 4800; Check bit: none; Data bit: 8; Stop bit: 1
Address modification
For example, changing the address of a sensor with address 1 to address 2, host → slave
Address code | Function code | Starting register high | Starting register low | Starting address high | Starting address low | CRC16 low | CRC16 high |
0x01 | 0x06 | 0x07 | 0xD0 | 0x00 | 0x02 | 0x08 | 0x86 |
If the sensor receives correctly, the data will be returned along the original path.
Note: If you forget the original address of the sensor, you can use the broadcast address 0XFF instead. When using 0XFF, the host can only connect to one slave, and the return address is still the original address, which can be used as an address query method.
Query data
Query the data (carbon dioxide) of the sensor (address 1), host → slave
Address code | Function code | Starting register high | Starting register low | Starting address high | Starting address low | CRC16 low | CRC16 high |
0x01 | 0x03 | 0x00 | 0x00 | 0x00 | 0x01 | 0x84 | 0x0A |
If the sensor receives the correct data, return the following data from the slave to the host
Address | 0X01 |
|
Function code | 0X03 |
|
Data length | 0X02 |
|
Register 0 data high | 0X0E | Carbon dioxide concentration: 3682ppm |
Register 0 data low | 0X62 | |
CRC16 low | 0X3D |
|
CRC16 high | 0XCD |

(1) Do not apply this device to systems involving personal safety.
(2) Do not install the device in a strong convective air environment for use.
(3) Equipment should avoid contact with organic solvents (including silicone and other adhesives), coatings, chemicals, oils, and high concentration gases.
(4) Equipment cannot be used in environments containing corrosive gases for a long time, as corrosive gases can damage sensors.
(5) Do not place the device in high concentration organic gases for a long time, as long-term exposure may cause the zero point of the sensor to drift and slow recovery.
(6) Prohibit long-term storage and use in high concentration alkaline gases.
(7) Although this product has high reliability, we recommend checking the equipment's response to the target gas before use to ensure on-site use.
