A Temperature Logger to Protect Sea turtles

Data loggers are small, battery-powered devices used to sense and store information in different situations. They include a microprocessor, data storage, one or several sensors and they can record information for a very long period. However, some data loggers do not include sensors, but have ports that allow a sensor to be connected. They are

MAX11311 – The Powerful Configurable Mixed Signal I/O

Programming MAX11311 is very easy. A nice GUI tool helps to generate the right register values. If you want to make a universal signal processing board with a good number of I/O, it often gets very difficult to select a correct microcontroller. Finally, when you select one, it either has less I/O than you need
