We’ll now explore the three most common types of motion sensors in more detail: passive infrared (PIR) sensors, microwave (MW) sensors, and dual technology motion sensors.
Passive Infrared (PIR) Sensors
Passive infrared (PIR) sensors, also known as passive infrared sensors, are devices capable of detecting body heat by identifying changes in temperature. Once activated, the PIR motion sensor detects heat and movement in the surrounding environment, creating a protective “grid.” When an object in motion obstructs numerous grid zones and the infrared energy levels fluctuate rapidly, the infrared sensor is prompted to sound an alarm. PIR sensors are the most common type of motion sensor used in home security systems because they are both reliable and cost-effective.
The distinction between PIR sensors and active ultrasonic sensors lies in their detection methods. PIR sensors detect variations in infrared energy, while active ultrasonic sensors employ sound waves to recognize movement. PIR sensors, configured to disregard insignificant alterations in infrared radiation, allow personnel to move without triggering alarms. This feature makes them a popular choice for home security systems.
Microwave (MW) Sensors
Microwave motion sensors:
Emit microwave pulses that reflect off objects and return to the sensor
Provide coverage of a larger area than PIR sensors
Continuously emit microwaves
Determine the exact distance between objects and the sensor by calculating the reflection rate of objects
Register any alteration in the object’s reflection rate due to movement as motion
While microwave sensors can monitor a wider area than infrared sensors, they are more susceptible to object interference and electronic interference. Calibrating microwave sensors can be advantageous, as it allows for increased or decreased sensitivity, which is especially useful in situations where pets are present. With their extended coverage and precise detection, microwave sensors are a powerful addition to any security system.
Dual Technology Motion Sensors
Dual technology motion sensors combine the strengths of both passive infrared (PIR) and microwave doppler radar technologies to improve detection accuracy. The PIR sensor recognizes alterations in infrared radiation, while the microwave sensor perceives modifications in the frequency of the microwaves. When both sensors detect movement, the alarm is activated.
The advantages of utilizing dual technology motion sensors include increased reliability, accuracy in detection, and a reduction in false alarms. These sensors can be employed for various purposes, such as home security, automated lighting, elderly care and monitoring, and business applications. Thus, dual technology motion sensors offer a dependable and precise means of detecting movement for a multitude of scenarios.
