Infrared sensors
Infrared (PIR)
— the principle of the PIR infrared sensor (from the English passive infrared sensor) is based on fixing changes in thermal radiation from surrounding objects. Such sensors accurately register movement, but are not immune from false alarms due to unforeseen heat flows and depend on weather conditions. To improve accuracy, there are sensor models that combine several PIR sensors, so that the sensor can analyze more changes and, accordingly, more accurately detect movement.infrared (PIR) | clear | Save List |
