What is the supply voltage?
What is the sensor?
Why would you choose a 50 year old opamp?
If you describe what you are trying to do, we will be able to help you choose the best approach,
its not clear that this circuit is useful to you without knowing all the details of your hardware
and what you want to do with it.
we are using the arduino uno board
we added a Bluetooth to our project
our project is about to make a wearable alcohol sensor to measure the alcohol level in your body.
here is the info of the sensor :
Breath Alcohol Sensor 1000 ppm
Breath Alcohol sensor designed for applications in:
Law Enforcement Breathalyzer
Evidential Breath Alcohol Testing
Portable Breath Alcohol Tester
It offers many benefits to your design
Small Size with Low Profile
Long Life (10 years expected life)
Fast Response (15 seconds typical)
Long Term Stability (2000 ppm overload)
Low Power (0 mW @ 0 mV bias)
Measure Breath Alcohol up to 1000 ppm
