MPX5700DP/MPX5500DP - Way to detect connected sensor (maybe using V1, V2 and Vex pins?)

Hi,

I wander if is it possible to hardware-detect which of the two MPX5700DP / MPX5500DP sensors is mounted on the board.

Can I use the V1, V2 and Vex pins with some circuitry between the sensor and the MCU to detect which sensor is connected? If yes, how? What type of signals are them?

I found in other questions (1, 2, 3) that those pins must be leave not connected.

But is there any possibility to use them for this scope, please?

Thank you in advance.

Bye,

Clem

Hi Clemente,

I am afraid there is no way to use these pins for this purpose and I cannot think of any other suitable possibility to achieve that, unfortunately.

Best regards,

Tomas
