micromax Sensor Interface

The micromax Sensor Interface is designed to complete small jobs with a microcontrollers help. Depending on the application, it can be arranged with different sensor interfaces (e.g. thermocouple amplifier, NTC amplifier). The sensordata can be processed in the microcontroller. The raw data can be filtered, linearized and sent to further CAN knots within the CAN bus interface. CANAerospace is supported.
