Smart Occupancy and Daylight Harvesting Sensors For LED High Bay Lights
Occupancy sensors are essential for reducing energy waste by automatically switching or dimming luminaires to only operate when they’re needed. These’smart’ devices can also implement daylight harvesting, which adjusts lighting according to available daylight for a balanced workspace at all times.
This sensor is designed as a combination with an LED driver and can be connected to 1-10V dimmable power supplies. It has adjustable settings such as hold time, day light lux level and detection area via DIP switches.
Mini Stand-alone HF Motion Sensors
Unlike traditional PIR (Passive Infrared) sensors that detect heat, these sensors use high-frequency electromagnetic waves to sense motion. Upon detecting movement within their detection range, they generate a signal that is used to trigger the lighting control system and adjust the connected lights.
This sensor is pretty small, and the design allows for mounting it inside of a light fixture or recessed into a wall or ceiling. The back of the sensor has two chamfered edges that you can use to mount it to a surface using outdoor flood lights adhesive strips, or to use screws to secure it. It also has a recessed hole to pass power through for hardwired options.
It pairs with the hub just like any other Z-Wave device, and I had no issues getting it to work with Home Assistant. The setup process is fairly straightforward – just install the batteries, and it automatically puts itself into inclusion mode, with a blue LED flashing. Once added, it shows up in HA with entities for the motion sensor and battery level.
The MC015S-D is a combination motion/daylight sensor that can be mounted within a light fixture to control halogen, fluorescent or LED lamps. It is configured via DIP switches to determine the daylight threshold and hold time, as well as which type of lights should be dimmed. The sensor can also be used with Eaton Groupmaster units to control multiple compatible luminaires.
Motion Detection
Suitable for a wide range of lighting applications including LED high bay lights (1-10VDimmable), this microwave motion sensor switches the light ON and OFF based on slight movements, allowing users to control brightness via the built-in switch or 1-10VDimmable LED driver. The hold time, corridor function and daylight lux level are adjustable via DIP switches.
The sensor is powered by 2.4G ZigBee protocol, and can be connected with Tuya smart devices, controlled via the Tuya App. Thanks to its international patented technology of low impedance antenna, the sensor effectively resists interference from 5G, Wi-Fi, Bluetooth and other wireless signals.
Shenzhen Merrytek Technology Co., Ltd (referred to as Merrytek) is a national specialized new “small giant” enterprise focusing on research and development of microwave intelligent control products. Founded in 2011, Merrytek has an experienced R&D team and production line that are capable of designing, manufacturing and distributing innovative motion sensors and integrated sensor LED drivers for lighting & electrical manufacturers, distributors, wholesalers, retrofit projects and professional lighting chain stores. The company also provides KNX intelligent lighting control solutions through Thinka, a leading smart home platform integrating visualisation and voice controls with Apple HomeKit, Amazon Alexa and Google Home.
Human Presence Detection
Human presence detection is the ability to recognize that there is an actual human nearby (or at least some type of recognizable human). Whether it’s turning on your kitchen light when you walk in or letting you use Merrytek Intelligent sensor your computer without pressing a button, this technology has a wide variety of applications. And when it works properly, it makes for a smooth background experience.
A variety of sensor types can be used for human presence detection. Passive IR sensors, for example, are already widely used in applications such as flipping the lights on when you enter a restroom or opening an automatic door at a grocery store. Ultrasonic proximity sensors are also sometimes used, but they typically have less detection range than passive IR sensors.
Using visual or IR cameras backed with facial-recognition software can also be useful for human presence detection. This is often done to help prevent unintentional button presses on devices such as earbuds or computers and can save power by shutting off when no one is around. This kind of functionality is also becoming available on select Tesla vehicles.
Daylight Detection
The intelligent sensor combines motion and daylight detection into one unit and can be fitted into luminaires for automated control. The sensors can turn the lights on when motion is detected and then reduce lighting levels when natural light is available, ensuring consistent illumination and energy savings. The smart controls, which can be built into the LED drivers or integrated into the bulkheads and non-corrosive fittings, are based on International Standards such as the Digital Addressable Lighting Interface (DALI), so they can easily be used with existing and new luminaires.
The MC003V micro-wave sensor combines both a high sensitivity motion detector and a daylight sensor to enable an effective solution for intelligent control of linear and batten LED lamps. The sensor has an easy to use DIP switch for setting the functions, such as the Detection area, Hold time, Daylight lux level, etc. It is also possible to achieve corridor function with 10% dimming.
The 0-10v interface in the sensor can match up with Merrytek stand-alone daylight sensor MS01 to implement daylight harvesting, it can automatically adjust the light output acoording to nature light, make sure the total light keep at certain level, and save energy without sacrificing visual comfort. This is an ideal solution when using the sensor with LED high bays or commercial lighting. The sensor has a patented design and can be mounted up to 15m, suitable for warehouse lighting.
