Hi,
I can surely design you the circuitry of fire detector with displaying the smoke level by selecting suitable transducer, amplifier and all other required components.
I have been doing electronics circuits designing and microcontroller programming for my clients at different freelancing platforms since 2015 (just new on Freelancer).
If you feel interested then, we can discuss further in chat.
Client satisfaction is my first priority, as I believe a satisfied client comes back for another work.
So, you don't need to worry about your design.
Looking forward to work with you. Thank you.
