The components that detect changes in the environments that IOT Devices are monitoring are the sensors. Sensors are available to detect almost anything that needs to be monitored. Examples include:
- Cameras and light detectors including non-visible wavelengths
- Motion and velocity recording and displacement detectors
- Accelerometers and tilt sensors
- Vibration detectors
- Electric and magnetic field detectors
- Fluid levels and leak detectors
- Humidity and moisture monitors
- Temperature monitors
- Fluid flow monitors in pipes
- Force detectors including for load, torque, strain, and pressure
- Chemical solution concentration detectors
- Chemicals leakage detectors
- Gas detectors for various gas types
- Acoustics and sound detectors
- Proximity monitors
