Electrochemical Detection Module ZE03 ZE03 is a general-purpose and high-performance electrochemical module. It uses three electrodes, electrochemical gas sensor and high-performance micro-processor. By installing different gas sensor, the module could detect relevant gas. It is with built-in temperature sensor to make temperature compensation, which makes it could detect the gas concentration accurately. It has the digital output and analog voltage output at the same time which facilities the usage and calibration and shorten the development period. It is a combination of mature electrochemical detection principle and sophisticated circuit design, to meet customers’ different detection needs.

Take ZE03-O2 (0-25%vol) as an example: 0%vol is corresponding to 1.5V, but the corresponding value of 25%vol should subject to inspection report, not 0V. Pin definition stable3. GND Ground VCC Power supply VO Voltage output RXD Series port input TXD Series port output Bottom view The meaning of V0 (Vout) : It means original voltage (linear) after amplifying circuit, rather than concentration value of current environment. If choose this pin test, users need to keep us informed when purchase, thus zero voltage Vout0 and test voltage Vout1 can be shown in the inspection report deliveried to customer with the modules together. Users can calculate gas concentration of current environment based on Vout0 and Vout1. Take ZE03-CO for example: zero voltage Vout0 = 0.6 V; in 200ppm CO gas,Vout1=0.9V, If the current voltage Voutx=1.2V, then the CO concentration: Name rules Model name: ZE03-X-X-X “Z” means module, “E ” means electrochemical type sensor, “03” means version, the first X means gas type, the second X means detection range, the third X means output way. Eg. “ZE03-CO-(0-1000)ppm-UART/VDC”,”ZE03-O2-(0-25)%VOL-UART/VDC”. “UART/VDC” means the output way is series port and analog voltage (non standard voltage, refer to stable2.)

Communication Protocol 1.General Settings Baud Rate 9600 Data Bits 8 bytes Stop Bits 1 byte check bits Null 2.Communication Specification The default communication type is active upload and it sends gas concentration every other one second (the concentration is 16 hexadecimal). Send 0x78 command to change communication type. After changing the communication type to 0x04 (Q&A type), only by receiving the 0x86 command (reading concentration value command), current concentration value can be sent.

Please do not take away or plug the sensor in the module. 2. It is prohibited to weld the pins of the module. The socket could be welded. 3. Sensor shall avoid organic solvent, coatings, medicine, oil and high concentration gases. 4. Excessive impact or vibration should be avoided. 5. Please keep the modules warming up for at least 5 minutes when first using. 6. Please do not use the modules in systems which related to human being’s safety. 7. Please do not use the modules in strong air convection environment. 8. Please do not expose the modules in high concentration organic gas for a long time. 9. Returned data of module serial port is real-time density of current environment, without standard gas, please do not use standard command, for it will cause calibrated data and returned data of serial port to zero. 10. To judge whether module communication is normal, it is advisable to use tools that can change USB to TTL(communication level 3V), debug assistant software via serial port, and determine it by communication protocol. 11. When choosing module, users should choose products of different applications and ranges. If there is no special requirement, products will use conventional range.
