This library is intended to provide a simple interface to the Microchip TC74 temperature sensor.
The TC74 is a simple device, availlable in a 5-pin TO-220 package, and communicates with the host via the I²C serial interface.
The core features (obviously) include the ability to read the temperature of the device.
In addition to this, the TC74 supports a standby mode, in which the A/D converter is halted, and the various data registers are "frozen", reducing the current consumption of the device from 200 μA to just 5 μA -- which is a relatively significant power savings.
