LM81 Description
The LM81 is a highly integrated data acquisition system for hardware monitoring of servers, Personal puters, or virtually any microprocessor-based system. In a PC, the LM81 can be used to monitor power supply voltages, temperatures, and fan speeds. Actual values for these inputs can be read at any time.
