In all but the most pedestrian of cases, you really should consider some form of input protection between your sensors and your computational platform. In my “Beginner’s Guide to Sensor Interfacing ...
A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...
This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...
