Identifying| Decimal valid range| Corresponding value| multiple
---|---|---|---
CO2| 400~5000| 400~5000ppm| 1
VOC| 0~3| 0~3 level| 1
CH2O| 0~2000| 0~2000μg/m3| 1

Temperature| 500~1150| 0~65℃| 10
Humidity| 0~1000| 0~100%| 10

1. The temperature value increases 500 from the actual measurement results, that is, 0 ℃ is corresponding to the number of 500.
   Temperature value = (DF7*256+DF8-500)/10

2. The measured value is represented by two bytes, the higher byte in front while the lower byte in the back.

3. After sending the inquiry command, if the response is received, the module will upload the data every second automatically. There is no need to repeat the command before the power is turned off.

Checksum and calculation

unsigned char FucCheckSum(unsigned char i,unsigned char ln){
unsigned char j,tempq=0; i+=1;
for(j=0;j<(ln-2);j++)
{
tempq+=i; i++;
}
tempq=(~tempq)+1; return(tempq);
}
CO2 zero point(400ppm) calibration

• To send：11 03 03 01 90 58
• Response：16 01 03 E6
• Function：CO2 zero point calibration
• Instruction: zero point means 400ppm，please ensure that the sensor has already been working for 20 mins at least at 400ppm concentration level before sending this command.

Start & Stop dust measurement

• Send：11 03 0C DF1 1E C2

• Response：16 02 0C DF1 CS

• Function：Start/Stop dust measurement

• Instruction：
  1、 Among send command, DF1=2 means starting measurement，DF1=1 means stopping measurement; 2、Among response command, DF1=2 means starting measurement, DF1=1 means stopping measurement; 3、 When the sensor receives the measurement command, it enters the state of continuous measurement by default.

• Send：11 03 0C 02 1E C0  //start dust measurement

• Response：16 02 0C 02 DA //the module is in “on-state dust measurement”

• Send：11 03 0C 01 1E C1 //stop dust measurement

• Respond：16 02 0C 01 DB  //the module is in “off-state dust measurement”

Cautions

1. The PM2.5 sensor on this module is suitable for the detection of dust particles in ordinary indoor environments. The actual use environment should try to avoid soot environment, excessive dust particles, high humidity environment, such as: kitchen, bathroom, smoking room, outdoor, etc. If used in such an environment, appropriate protective measures should be added to prevent viscous particles or large particles from entering the sensor, forming a buildup inside the sensor, and affecting the sensor’s performance.
2. The module should avoid contact with organic solvents (including silica gel and other adhesives), coatings, pharmaceuticals, oils and high-concentration gases.
3. The module cannot be completely encapsulated with resin material, and it cannot be immersed in an oxygen-free environment, otherwise the performance of the sensor will be damaged.
4. The module cannot be used in the environment containing corrosive gas for a long time. Corrosive gas will damage the sensor.
5. The module needs to be warmed up for more than 3 minutes when it is powered on for the first time.
6. Do not use this module in systems involving personal safety.
7. Do not use the module in narrow room, the environment should be ventilated well.
8. Do not install the module in a strong convection air environment.
9. Do not place the module in high-concentration organic gas for a long time. Long-term placement will cause the sensor zero point drift and slow recovery.
10. It is prohibited to use hot-melt adhesive or sealant to seal the module with a curing temperature higher than 80℃.
11. The module should be away from the heat source, and avoid direct sunlight or other heat radiation.
12. The module can’t be vibrated or shocked.
