sensors

 Hi,

we are developing a circuit where we have to integrate multiple sensors to the controller. we have tried integrating two temperature sensors together in cc430.But the readings that we are getting are not proper for the second sensor.could anyone suggest a solution for this.

    Hi

    Are you referring to the integrated temperature in the CC430 or have you connected external sensors to the MCU? If so we need more details on what kind of sensors how they are connected and what the readings are.

    For the internal temperature sensor, please look at the example codes (www.ti.com/.../slac279). The cc420x613x_adc12_10.c shows how to use this sensor.

    Hi,

    thanks for the reply. i am trying to integrate 2 sensors externally. I am  currently using MA100 thermistor, i would also like to know how many sensors can be integrated externally to cc430 at a time.

    thanks.

    Hi

    Using a thermistor would require the use of the ADC on the CC430 so then the number of sensors like that would be limited by the number of ADC channels on the CC430. For other sensors it will depend on the type of interface they have like SPI or I2C and so on.
