rir - reflective infrared sensor RIR Reflective Infrared presence/proximity/motion detector with self programming detection range. Unlike a Pyroelectric Infrared sensor (PIR) that is used in many motion detectors, the Reflective Infrared sensor (RIR) does not detect long wavelength infrared radiation emitted by a human or animal body.
Dual Technology Sensors Similarly, Dual Technology sensors are smart solution that can help reduce energy waste and provide an additional level of convenience for occupants. They work using a combination of PIR and Ultrasonic technology. As individuals move throughout a given space, Ultrasonic wave analysis and the Doppler effect help detect indirect motion while passive infrared sensors monitor presence directly.
Motion sensor: Position sensor: Proximity sensor: 1: The motion sensor is also called as the IR sensor: Position sensor is also called Passive IR sensor: The proximity sensor is called by many different names: 2: Figure: 3: Different types of sensors: 1.

Alcohol Sensor MQ-135 Gas Sensor. The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and smoke. The boost converter of the chip MQ-3 gas sensor is PT1301. The operating voltage of this gas sensor is from 2.5V to 5.0V.
ambient temperature sensor is built into the electronic measuring device near the point where the reference junction is attached. The ambient temperature is then added to the thermocouple differential temperature by the measuring device in order to determine and display the actual measured temperature.
An ultrasonic motion detector is a device that can detect movement of people or objects within a limited area. It senses motion by analyzing sound waves in its environment. Some just listen for sounds, while others send out ultrasonic signals and analyze how they are reflected back.
Critical to vibration monitoring and analysis are machine-mounted sensors. Three parameters representing motion detected by vibration monitors are displacement, velocity and acceleration. Mathematically related, the parameters can be taken from a variety of motion sensors.
