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
