Left side value of detection range (zero point) is corresponding to left side value of voltage output range ,BUT right side value of detection(max detection value ) is NOT corresponding to the right side value of voltage output range.
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, other values like 0.1V or 0.2V are possible.

The meaning of VO (Vout) : It means original voltage (linear) after amplifying circuit, rather than concentration value of current target gas in environment. If choose this pin test, users need to know when purchase, the zero voltage Vout0 and test voltage Vout1 can be shown in the inspection report delivered to customer with the modules together. Users can calculate gas concentration of current target gas in 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 detected gas, 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

Parity
None
2.Communication Specification The default communication type is active upload and it sends gas concentration once every second (the concentration is 16 hexadecimal). If you want to switch to Q&A mode, please send 0x78 command, to change communication mode to 0x04(Q&A mode), then current concentration will be sent by module after it receiving 0x86 command (reading concentration), suggested communication cycle is 1s.
3.Communication Commands The default mode is active upload mode, the sensor will send gas concentration actively as follow without sending any command by users.

Cautions
1. 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 concentration of current target gas in environment, If you don't have standard gas, please do not use standard command, for it will cause calibrated data is clear

away and returned data of serial port is not accurate. 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.
