When no gas digital output is 1 and analog output gives 1023 max value. When gas is present digital output is 0 and analogue output is much less than 1023. Using potentiometer on chip we can control the turning OFF point of digital pin at some value of analog pin. The sensor needs a load-resistor at the output to ground. Its value could be from 2kOhm to 47kOhm. The lower the value, the less ...
2014-08-03· A sensor module like the MQ-135 has an analog output voltage, which you can feed to an analog input of your Arduino. Most modules also have a digital output, which can be tuned using the onboard potmeter, which triggers when a certain level has been reached. These sensors come calibrated (to a certain amount) but calibrating them yourself will be complicated as you need to replicate an ...
The MQ131 ozone gas sensor makes it easy to monitor ozone concentration levels using our I2C Mini Module form factor.
