What are PIR motion sensors and how do solar security lights use them?
Posted in: Commercial Solar Lighting, Residential Solar Lighting, Solar Security Lights | September 7, 2020
A PIR motion sensor (PIR stands for “pyroelectric, or passive, infrared”) is a device that detects movement and heat. These devices, also known as solar PIR units or IR sensors, create a grid that is triggered by changes to infrared energy levels.
PIR Motion Sensors are More Common Than You Think
Solar security systems utilize various motion sensing technologies, but PIR sensors are the most common. Though most often used for security and safety purposes, PIR motion sensors are also common in automated lighting systems, where they are known to save energy by limiting electricity in unoccupied areas. They are also found in automatic doors, plumbing, and ticketing machines.
Why Choose a PIR Motion Sensor?
PIR sensors come in various forms, most of which are small, inexpensive, and easy to install. Most PIR units in lighting systems are not physically connected to a solar panel, meaning a panel can be adjusted for maximum sunlight and still power security lights facing opposite directions. Most models contain multiple lenses and sub-lenses for maximum detection and range.
How do Motion Sensors Benefit Solar Security Lights?
Whether you want to enforce a teenager’s curfew, keep four-legged critters away, or deter prospective intruders, PIR motion sensors are an integral feature in any security alarm or automated solar lighting system.
PIR sensors are linked directly to your security system, so you will be alerted if they detect irregularities. The PIR detects changes in temperature and radiation levels in the sensor’s field of view. If any change is detected, your PIR motion sensor will trip your lighting system as your security system receives notice of the irregularity.
At the recommended 700-1300 lumens, the power of a solar security floodlight is typically limited by its battery life. However, with PIR sensors, solar security floodlights are only activated at specific times, saving battery life in the process.
What Kind of Maintenance Does a Solar Security Light with Motion Sensors Require?
No electrical wiring or electrician is required to maintain a solar security light with PIR motion sensor. All Gama Sonic products have a 2-year limited warranty and battery replacement is recommended after 1,000 cycles or approximately 3 years.
Where Can I Put Up A Solar Security Light with Motion Sensors?
In terms of placement, PIR sensors should be kept at least ten feet from heating vents. They are most effective when placed to detect movement near an entry or exit point such as a back door or garage door. It is important to consider the route a burglar might take and place sensors so obscured areas and parallel walls are within range. Once your motion sensor is mounted in an area that receives 4-6 hours of direct, unfiltered sunlight on most days, for maximum effectiveness, you can connect it to your home security system and adjust its settings. It is important to remember to clean your PIR sensor on a monthly or bimonthly basis, removing all dust and debris from its surface to avoid infrared interference.
Additional Tips for PIR Motion Sensors
- If you have pets, consider getting a pet immune PIR motion sensor. These sensors can be programmed according to an animal’s height and weight to avoid false alarms.
- A PIR sensor is like a beam of light: anything that blocks its path and creates a shadow will likely break the sensor’s grid.
- Consider placing your PIR somewhere without an overhang (such as a porch roof or carport) to ensure maximum visibility.
