Hardware Monitor is an application to read out all accessible hardware sensors in Macintosh computers. Currently more than 100 different Macintosh hardware sensors and more than 200 hard drive temperature sensors are supported. The program can visualize the history graphs of the readings, display measured values in a large variety of fashions, or announce readings by speech output. It can also store and export readings. Depending on what sensors are built into your Macintosh system, the following data can be accessed:
Temperarature readings at different locations
Battery data of portable computers
Voltage sensors
Current (amperage) sensors
Fan speed sensors
Sensors for pulse-width controlled fans
Power and load sensors
Ambient light sensors
User-defined artificial sensors to monitor the operating system
Hardware Monitor is electronically distributed software. You can download the product and test it before you decide to purchase an unrestricted usage license.
