Detection Range
The detection range is the zone in which the PIR sensor can detect motion, usually between 5 and 12 meters. The longer the range, the larger area the sensor will cover effectively. Sensor placement should be optimized to ensure the coverage is maximized in required areas without producing any blind spots.
Field of View (FOV)
The field of view of a PIR sensor is the angle at which it can detect motion, typically around 90 to 180 degrees. Wider FOV allows the sensor to monitor more space, which, of course, reduces the number of required installations.
Sensitivity Levels
This is basically how responsive the sensor is to movement. The sensitivity levels can be controlled according to the desired level of detection needed. High sensitivity may be needed in areas requiring additional security, whereas low sensitivity might be used in areas with constant movement.
Temperature Range
Zigbee PIR motion sensors usually perform within a variety of temperatures, mostly from -10°C to 50°C. Outdoor sensors need to be able to deal with extreme weather conditions so that their performance will not be degraded at all.
Power Supply
Many PIR sensors are powered by a battery, mostly lithium or alkaline types, but some can be powered by solar energy or wired connections. Battery-operated sensors require constant monitoring of battery levels to maintain effective functionality.
Regular Cleaning
The lens of the sensor can be affected by dust, dirt, and debris, which affects its efficiency. It is recommended to clean the lens at least every three months so that optimal beaming can be maintained. Use a soft, damp cloth to remove any deposits on the lens.
Check for Battery
If installed on a device powered by batteries, the state of the batteries should always be checked and changed regularly, as they are the main source of power for the device. Depending on usage intensity, some can be done monthly or quarterly.
Inspect Settings
It is also recommended that sensor settings be inspected from time to time, mainly when the performance is not up to scratch. Ensure that sensitivity, range, and FOV are set accordingly to the requirements of the area. The software setting will need to be adjusted, especially if the sensor is incorporated into a smart home system.
Environmental Checks
Other factors in the environment, like temperature, humidity, and even physical obstructions, can affect how well the PIR motion sensor works. These should be taken into account when installing a sensor, and adjustments should be made if the conditions change around it.
Firmware Updates
For PIR motion sensors that are on the network, firmware updates should be carried out regularly to improve their performance and deal with possible security threats. This is done to ensure that the sensor works at its peak and that any possible bugs are fixed.
The motion sensors can be integrated with smart systems to provide security features such as automatic lighting, alarm, and surveillance.
