Sensors
Sensors is a Mac utility from Sascha Simon used to view hardware sensor readings such as temperatures, voltages, power data, and fan speeds.
What is Sensors?
Sensors is a macOS utility focused on showing live hardware sensor information from your Mac. It is used to monitor values such as temperatures, voltages, power readings, and fan speeds so you can keep track of system health and activity while you work. This kind of app is useful for users who want a clearer view of thermal behavior, cooling performance, or general hardware conditions during everyday use, heavier workloads, troubleshooting, or benchmarking. On Mac, tools in this category are commonly used alongside performance monitoring and maintenance workflows. Sensors fits the utilities category and is aimed at people who want quick access to low-level system readings in a simple desktop app.
Key features
- View live temperature readings from available system sensors
- Check fan speeds in real time
- Monitor hardware values such as voltage and power data
- Keep track of thermal behavior during demanding workloads
- Use sensor information while troubleshooting cooling or performance issues

Safety overview
Status: Mostly safe
This is a legitimate Mac utility for hardware monitoring. Apps in this category may need access to detailed system information, and sensor features can depend on helper components or system-level reading methods that are normal for this purpose. It is generally fine to keep if you use it, but remove it if you no longer need hardware monitoring on your Mac.
Recommendation: Keep Sensors if you use it to watch temperatures, fan speeds, or other hardware readings. If you do not use system monitoring tools, you can remove it without affecting macOS beyond losing its sensor-viewing features.
