Hey!
i have to decide whether what i want to do is possible and i need some guidance. i need whether anyone did that or have examples that it is done.
i want to connect approximately 256 sensors to arduino. i tought i can do that with multi layered muxes, but i have concerns about
- driving the 256 sensors, how can i manage the current and the volt? those sensors i have seen was generally connected as alone to arduino.
- reading 256 sensors one by one , do i loose real time efficieny
- all the sensors have analog outputs, require approx 5V VCC.
- is it possible to demux the volt too? has anyone done that ? or would it be not feasibel since after you applythe volt it iwill require a set up time to sense.. i mean i can not probably just apply the volt and try to read the output ?
- is there examples for this , a reliable chip which already deals with current volt output selection and you just connect the sensors to that chip
input is blow, air flow on a surface.. i want to know whichpart of the surface is blown into.. open to suggestions.
and i will also put alcohol sensor sparingly to detect alcohol in blood.
