• Attention to the module should avoid contact with organic solvents (including silica gel and other adhesives), paints, chemicals, oils, and high concentration gases.
• The module must not be subjected to excessive impact or vibration
• The module should be preheated for more than 5 minutes for the first time, and it is recommended to preheat for more than 24 hours if the module is not used for a long time.
• Do not install the module in a strong air convection environment.
• Do not place the mold in a high concentration of organic gas for a long time.

• Pre-calibration(With build-in MCU and temperature sensor)
• High sensitivity and Accuracy to toxic gas
• Long life, low power consumption
• Good stability
• UART and analog voltage signal output

Specifications

• Portable gas detector
• Fixed gas alarm and detector

• 1 x 101020912, Grove Oxygen Sensor Pro-GGC2330 (Pre-calibration)
• 1 x Grove Cable

Simple Test:
Here we will show you how this Grove - Oxygen Sensor Pro(GGC2330-O2) works via a simple demo. First of all, you need to prepare the below stuffs:

Seeeduino Cortex-M0+	Grove - Oxygen Sensor Pro(GGC2330-O2)	Base Shield

Connection

Thanks to the benefit of Grove series modules, you don't need to make soldering or bread board, what you need to do is connect the modules to the right port of Base Shield. For this demo, we have only one Grove module.

• Grove - Oxygen Sensor Pro(GGC2330-O2) is an analog input module, we connect it to UART in this demo.

Upload the code to Arduino

Copy the below code to Arduino IDE.

void setup() {

 Serial.begin(9600);
 Serial2.begin(9600);
}
void loop() {
 if (Serial2.available()){
   uint8_t begin_code = Serial2.read();
   delay(10);
   uint8_t state_code = Serial2.read();
   delay(10);
   uint8_t high_code = Serial2.read();
   delay(10);
   uint8_t low_code = Serial2.read();
   delay(10);
   uint8_t check_code = Serial2.read();
   delay(10);
   uint8_t checkk_code = Serial2.read();
   delay(10);
   uint8_t checkkk_code = Serial2.read();
   delay(10);
   uint8_t checkkkk_code = Serial2.read();
   delay(10);
   uint8_t checkkkkk_code = Serial2.read();
   delay(10);

   if(begin_code == 255 && state_code == 134){

     float O2_val = ((high_code * 256) + low_code) * 0.1 ;
     Serial.print("O2: ");
     Serial.print(O2_val);
     Serial.println(" %");
     }
   }
   while(Serial2.read()>=0);    //clear buffer
}
