Six Types of Occupancy Sensors Explained |

Apr 01, 2010· PIR detectors, the simplest type, have a sensor face that measures different air temperatures in a room. PIR detectors are considered passive because they do not emit any light, sound or heat. Computerized sensors inside the detector compare the average room temperature with the increase in heat that occurs when a human walks past the sensor.

What is a Sensor? Different Types of Sensors, Applications

Apr 02, 2021· The other type of IR Sensor is a Reflective Type IR Sensor. In this, the transmitter and the detector are positioned adjacent to each other facing the object. When an object comes in front of the sensor, the infrared light from the IR Transmitter is reflected from the object and is detected by the IR Receiver and thus the sensor detects the object.

Best Practices: Occupancy Sensor Placement and Technology

PIR Sensor False Triggers PIR sensors utilize infrared radiation impinging on the sensor to detect motion. A change in temperature in the space can result in an erroneous reading from the sensor. HVAC vents that cause moving air across the sensor, or situations that cause the sensor housing to heat up and cool down, will cause false triggers.

PIR Motion Sensor Tutorial : 8 Steps (with Pictures ...

PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.
