I am doing a project with an arduino and an array of sensor, and I would like to be able to detect which sensor is connected to my circuit.
If I connect a temperature sensor it will be able to output the temperature [C], but if it was a force sensor it would output the result in newton [N]. The problem is to detect which sensor is connected, without having a micro controller connected to the sensor circuit that would send some bytes that was unique for different kind of sensor.
My though is to include a resistor in the sensor circuit and thereby measuring what kind of sensor that is connected. Would that be possible?
In addition to this:
If I have lets say 4 jack connectors connected to the arduino, and I made some sensor circuits which also had a jack connector and I would like to be able to connect any sensor to any jack port on the arduino and get the results, how would you construct the sensor circuit.
As far as I can tell there are some sensors which will output some milivolts when used and some which can be measured by resistance, but I want the sensors to be read by the same circuit which would require some sort of tweak to the sensor to have them either output milivolts or output resistance.
The sensors we are talking about could be (pH-meter, temperature, force, decibel ect...)
Hope that someone can help.
