Hi, I'm trying to make a touch sensor pad using a grid of temperature sensors that would be covered with a thin, heat-conducting rigid sheet. I need these sensors to be able to pick up the temperatures on the sheet above them when the sheet is touched with the fingers and give the readout to the microcontrollers that will be polling them. This will mostly be used in room remperature conditions. Do any of you know of a good temperature sensor for this kind of application? Thanks in advance.
