Sensors

Sensors offer many different ways to control light output of your luminaires. 

We have both stand-alone sensors for you to upgrade your luminaire, and also LED drivers with intergrated sensor for easy and cost-effective installation.

Microwave motion sensors

Merrytek microwave motion sensors are active motion detectors for luminaires. Besides the automatic ON-OFF control, Merrytek offers a wide range of microwave motion sensors with more energy-saving functions, such as 2-step dimming, 3-step dimming and RF communicating. Users can select the exact solution for numerous lighting applications.

Sensor Principle

The high-tech sensor works on the principle of the Doppler effect. The sensor emits a signal at a 5.8GHz high frequency and receives its echo. If a movement in the detection zone changes the echo pattern, the sensor responds and switches the light on. In addition, due to the built-in daylight sensor, it can also read the lights level. The sensor will not switch on the light if there is sufficient natural light.

Daylight harvesting

Merrytek's sensors are cabable of detecting artificial light and natural light from each other and therefore offer effective options for energy saving.

Merrytek Sensor Functions

Normal motion detecting

The sensor only detects a greater range of movement, such as walk.

Minor motion detecting

The sensor can detect minor movements, such as typing on a keyboard or taking notes.

Zero-crossing point operation

Helps protect the sensor against in-rush current when switching on/off.

Weather resistant

Normally, winding, breezing and raining can trigger microwave motion sensors. Merrytek use the latest 4th generation microwave detection technology for outdoor sensors to avoid interference from the elements.

Identifying of artificial LED light and natural light

Merrytek's patented daylight detecting sensor is able to identify and distinguish between artificial light and natural light. It can be installed in a LED luminaire and achieve daylight harvesting for increased energy savings easily.

Dry-contact

Dry contact sometimes is known as “Potentio-Free” or “Volt-Free”. It opens or closes contact without any current or voltage.
