Need to make a device that connects with 50-60 pressure sensor (ECU/PLC)??

[dbaid]

Hi,

Want to make a device that connects with 52-60 sensors,and computes and stores a output.
The calculations that are needed to be done are not very many and not too much.

The device also needs to be connected to a GPS.

Thanking the guys who help out,

Thanks ,
Divyakant.

Use Multiplexer, 8 input or 16 input multiplexer.

Hi,

It depend on the distance of the sensors. Maybe a digital bus system has benefits. But surely it is more complex than with the multiplexers.

Also you need to calculate expected sample rate, low pass filters (noise, anti aliasing...), and settling time when you switch from one signal to the other.

To ease the design you can use 4 pieces 16:1 muxes, all control lines conected, and the signal outputs to a ucontroller with 4 adc inputs.

Good luck
