The Multiple Sensor Interface is a simplistic sensor interface to USB, RS485, GPIO, that allows to make measurements of a variety of sensors based on the variation of inductance, resistance, capacitance, frequency using exactly the same connector and same electronic interface circuit between the sensor and the microcontroler. The same device also provides some additional connectors for small voltage measurement. Any sensors for the measurement of distinct phenomena can be used as long the sensor output is based on inductance, resistance, capacitance, frequency within the measurement range of the device, obtaining a variable precision depending of used sensor. The device is not meant for precision/accuracy measurement, is meant to be a reusable hardware that can be reused for most distinct situations, providing to the user more freedom of sensor selection as well more options for device/system maintenance or reuse.
