LM40 - Hardware Monitor
The LM40 is a hardware monitor that measures 3 temperature zones, 5 voltages and has a single-wire interface compatible with National Semiconductor’s SensorPath bus.
SensorPath data is pulse width encoded, thereby allowing the LM40 to be easily connected to many general purpose micro-controllers.
