7 Conclusion

This application reports shows how to interface the TMP107-Q1 temperature sensor, or similar, over the standardized CAN or RS-485 physical layer. The circuit uses an inexpensive TLC555-Q1 timer with integrated comparators for the flow control. This solution eliminates the microcontroller and allows for long-distance communication in automotive and industrial applications.
