Arduino and Ozone sensor Botland - Robotic Shop

The MQ131 ozone gas sensor makes it easy to monitor ozone concentration levels using our I2C Mini Module form factor. The MQ131 is connected to an ADC121C 12-Bit Analog to Digital converter, which is capable expanding to 9 gas sensors per I2C port using just two address jumpers (making full use of the floating address system).

Arduino and Ozone sensor Botland - Robotic Shop

Diagram of connection between ozone sensor and Arduino Uno. Operation. The DOUT output is digital. By default it is in a low state, but when ozone particles are detected it goes into a high state. The sensitivity can be adjusted with a built-in potentiometer. The AOUT output works analogue and decreases its value as the ozone concentration increases (it is inversely proportional to it). In the ...
