  • I have a thermistor connected to one of the ADC's but I am having quite a bit of trouble with noise.

    As a test I have setup the circuit with another resistor in replacement of the thermistor bead but I cannot seem to get the readings to a stable state. I have in addition tried using a 100nF capacitor across the input which helps to some degree but not enough.

    Ideally I would like to stabilise the temp to at least one decimal place.
    I would assume some sort of software filter, any suggestions?
