Electrochemical Carbon Monoxide Gas Module ZE18-CO Profile ZE15-CO is a general-purpose and miniaturization electrochemical carbon monoxide detection module. It utilizes electrochemical principle to detect CO in air which makes the module with high selectivity and stability. Built-in temperature sensor can do temperature compensation; and it has digital output and analog voltage output. It is a combination of mature electrochemical detection principle and sophisticated circuit design. Features High sensitivity, High resolution, Low power consumption, Long lifespan Supply UART, Analog Voltage...

Preheating State: 1.25S high level, 1.25S low level cyclic output 30s. It output low level after preheat completed . Communication Protocol 1. General Settings Table 3 Baud Rate Data Byte Stop Byte Check Byte 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. Table 4. Initiative upload data format Byte0 Start Byte Concentration (High Byte) Full Range (High Byte) Full Range (Low Byte) Gas Concentration = low 5 bits of high bit of gas...

3. Check sum and calculation Check = (negation(byte1+bye2+……+byte7))+1 Please refer the following example: 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); } DO NOT insert or extract the sensor on the PCB board. DO NOT change or move the electronic part on the module. Avoid sensor contact with organic solvent, coatings, medicine, oil and high concentration gases. Excessive impact or vibration should be avoided. Please keep the modules warming up for at least 5 minutes when first...
