A sensor is the part of an IoT device or system that collects information about the environment. For example, a temperature sensor in a smart HVAC system collects temperature data. Some common sensor types in IoT are: Passive Infrared (PIR), Ultrasonic, Pressure, Level, Temperature, Humidity, Gas, Light (Optical), Motion (PIR and Microwave), Magnetic Field (Hall Effect), Smoke/Fire, Flow/Velocity, pH Sensor, Water Quality Sensor, etc. Related Test: IOT Practice Test: Handling Actuators
