【Parameters】

【Function description】

Big motion signal active Minor motion signal maintain
Human presence: detect the human body in the detection area to carry out big movement signals (walking) to trigger the induction and output high level (such as control lights on and off), and then detect minor motion signals (body leaning forward, backward, limb swinging, shaking the head, typing, playing mobile phones and other minor motions.) as well as the detection of human respiratory vital signs caused by the abdominal cavity, chest expansion etc to maintain output high level (such as control lights always on)

Human absence: no signal detected in the detection area and output low level (control lamp off)

【Initialization】

After power on, the sensor automatically turns on light at 100% brightness, and self-check for 10s. During the initialization, the sensor is not able to detect movement. It enters sensing mode after initialization, and during which, the lamp maintains at 100% brightness.

【Default setting】

Sensitivity: 100% Hold time: 5s Daylight sensor: Disable Stand-by period: 0s Stand-by dim level: 20%

【Application Notice】

l The sensor should be installed by a professional electrician. Please turn off the power before installing, wiring, changing the configuration.

l The product has good penetration ability to plastic, wood, etc., but the microwave module antenna should not have metal accessories or metal shells, glass shells, etc.in direct front or nearby, otherwise it will affect the antenna transmission and reception.

l The sensing distance will be affected by the installation height, the size of the object to be detected, the speed of movement, the impact of the installation environment, and the sensing distance in different directions will have a certain degree of variability.

l The daylight threshold is in a sunny environment, no shadows, and ambient light diffuse reflection conditions. In different periods, climates, and environments, the daylight value detected by the light sensor may be different.

l The installation distance of the product is recommended to be more than 1.5m; the installation distance between the product and the router should be more than 1.5m, so as not to cause interference to the normal operation of the microwave sensor.

l The mounting plane of the product (e.g. aluminium substrate, PCB board) needs to be at a certain height difference from the antenna plane of the microwave module, and the antenna plane of the microwave module should be higher than the nearby plane by more than 5mm in order to achieve the best detection effect.

l DC regulated power supply with stable output voltage, low current and ripple coefficient must be used, the ripple of the power supply should be less than 50mV, and the minimum load current of the power supply should be more than 120mA, and it is also recommended to set up an electrolytic capacitor of not less than 100uF at input power supply VCC terminal.

l Product installation as far away as possible from large metal equipment, pipelines, air conditioning vents, exhaust vents, smoke machines and other scenes, so as to avoid equipment vibration affect the detection effect.

l Microwave module should avoid close to the AC drive power supply, be away from the drive power supply rectifier bridge, transformer, switching tubes and other high-power devices, to avoid high frequency signals interference to normal operation of the microwave module.

l Product design: the antenna surface of the microwave module and its nearby circuits to avoid the flow of large currents, avoiding transformers or high frequency components nearby, distance should be more than 10mm as far as possible.

l When wiring, the antenna side and the component side on the back of the product should not be covered by wires or have large currents flowing through, so as not to affect the normal operation of the sensor.

l The front of the product and nearby can not be equipped with metal accessories or glass block, so as not to affect the normal operation of the sensor, while the thickness of the plastic as far as possible to choose less than 1mm, too thick will affect the detection of microwave modules and directionality; microwave antenna plane and the shell distance should be greater than 3.2mm

l The antenna surface of the product and the metal plane (aluminium substrate, iron shell) need to be a certain height difference, the recommended distance is more than 0.5mm.

When product structure, power supply mode/circuit, sensor antenna front cover, etc. changes, pls notify the sensor manufacturer to confirm, so as not to cause the product to work improperly. Otherwise, the manufacturer does not bear any corresponding responsibility for the abnormality.

Core Technologies Advantages

Microwave Motion Sensor

Based on principle of Doppler effect and 5.8GHz microwave detection technology for motion detecting. Currently, Merrytek developed over 200 models motion sensors which support long detection area up to 20m, 15m mounting height and outdoor use motion sensors. Those are at the leading position in our industry.

Typical products: MC and MLC series.

LifeBeing Presence Sensor Technology

As only support big range movement detecting, microwave is normally used in the places people only make a brief stay, for example, corridor, stair well, warehouse and parking lot. Merrytek use high frequency microwave and unique programming, microwave sensors are able to detect very minor movements, i.e. typing and breathing to avoid false reporting and underreporting. Merrytek provides series sensors with KNX, DALI, 485 and Bluetooth for building automation.

Application: office, classroom, meeting room, kitchen, rest room and so on.

Typical products: MSA series.

Daylight Sensor

As always, Merrytek concentrates on simple intelligent light solutions and luminaries’ construction. We successfully completed an in depth study of our patented self-adaptive LED drivers which can identify artificial light and natural light. We therefore can supply an extremely cost-effective and energy saving daylight harvesting solution for office use.

Typical products: MS series

Flicker-free DALI/1-10V Dimmable LED Driver

Replacing traditional incandescent and fluorescent lights with more efficient and longer-lasting LED-based solid-state lighting (SSL) is an undeniable trend in the lighting industry. However, since SSL fixtures are directly connected to an AC power supply, (consistent with legacy lighting), there is a risk that 100-Hz or 120-Hz flicker could occur as a result of the driving AC current’s fluctuation at the supply's output. Flicker can make people uncomfortable, causing headaches, stress and fatigue even though the human eye may not detect the flicker.

Currently, most of dimmable LED drivers have flickering issues (especially PWM types), when dimmed below 5%. Merrytek newly-developed flicker-free dimming technology can eliminate nearly all flickering and even when dimmed to 2%.

Typical products: ML and KL series.

Emergency Pack for LED Lighting

From 2016, Merrytek has dedicated to quality emergency pack for LED fittings, such as ceiling lights, tri-proof lights, down lights and panel lights. Top quality battery will be use in all our range and make sure excellent life time and good reputation.
