Ultra low power Analog Sensor Interfaces

There are several sensor elements using a standard interface like 4-20 mA, I2C or SPI. In addition, there are analog sensor elements like k-type thermocouples. It would be desired to be able to connect such elements to a wireless device to store the readings in the cloud. A flexible solution allowing a wide range sensor elements to be connected would be useful.

The assignment will be:

  • Study the most used analog sensor interfaces
  • Investigate the properties of each of them and rate them with respect to accuracy, calibration requirements and power dissipation
  • Plan a design supporting one or more of the interfaces
  • If time, build a PCB and demonstrate operation

The assignment is well suited for continuation into a Master Project

Feel free to make direct contact with the Disruptive Technologies external supervisor under it this sounds interesting.
