The most popular sensors now available on the market include: • Microwave - detect motion • Passive Infrared (PIR)- detect temperature • Photocell – uses the natural light from the sun to detect light and dark
Move to Illuminate - Microwave Sensors
Microwave sensors are an excellent solution for energy saving. They operate in a similar way to sonar in that they emit a microwave signal and measure how long it takes for the signal they send out to bounce back to the sensor. When something moves in the detection zone, this disrupts the signal and triggers the light to switch on. The microwave sensors are sensitive and so can detect movement and trigger the light to switch on in an instant. Microwave sensors can cut a substantial amount of energy wastage by automatically turning the lights off when the area is left unoccupied, ensuring that the energy required to light a space is only activated when occupied. They are the ideal solution for large commercial or industrial spaces.
Turn Up The Temperature - PIR Sensors
In contrast to the Microwave sensor, the PIR sensor detects infrared energy produced through body heat. They do this by measuring infrared light which is emitted from objects that generate body heat such as humans and animals. When the sensor detects temperatures returning to the original state, the lights will switch off, making it highly convenient and cost effective for the end user by reducing their electrical output. PIR sensors will only activate when heat movement is detected and so won’t activate unnecessarily. PIR is the perfect solution for domestic dwellings.
Just like Natural Daylight – Photocell Sensors
There are few sensors which are as energy efficient and effective as photocell sensors. These nifty little sensors will activate based on changing natural light levels, turning lights on at dusk or dawn. Photocell sensors use semiconductors to control electric current. When exposed to enough light, currents begin to flow and triggers the fitting. In many products, the photocell sensor is adjustable to the amount of light required which allows you more flexibility with how the sensor functions. These sensors are utilised for a range of applications but are commonly seen in turning outdoor lights on at sunset and off at dawn. These sensors are an excellent energy efficient addition to your lighting fittings as you can be assured that lights won’t turn on needlessly.
