40xv Oxygen Gas Sensor O2 Sensor for Gas Detector Based on ELECTROCHEMICAL Principle

40xv Oxygen Gas Sensor(O2 Sensor) for Gas Detector


>>> Product description


After the analog signal output by the oxygen electrochemical sensor is amplified by the module, it is sent into the ADC acquisition port of STM32 single-chip microcomputer. After the filtration operation inside the STM32 single-chip microcomputer, the oxygen concentration in the air is calculated and then output from the serial port. The module is compatible with 40XV,Me2-O2,AAY80-390R and other electrochemical probes. Module uses high precision rail-to-rail amplifier AD86XX amplifier circuit, integrated ARM Cortex M0 32-bit CPU,12-bit ADC sampling, serial port output oxygen concentration, can be calibrated through the serial port output value,baud rate 115200.

Electrochemical gas sensor is based on the principle of electochemistry,using the measured gas on the sensor working electrode and electrode corresponding REDOX reaction and release charge,through the external circuit to form a current, current size is proportional to the concentration of gas,so as to achieve the quantitative measurement of the target gas.


Applicable


It can be used in automobile, laboratory,coal mine, steel, petrochemical,medical and other measuring environments.
