Open Source for Mac OS X

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
