Microwave Sensors. The Ultimate Buyers Guide

Microwave Sensors

HF Motion Sensor Introduction. Microwave Technology
Completely built-in the lighting fixture, the motion sensor utilizes Doppler principle and RADAR technology to detect moving objects at certain speed & reflection surface, and gives output control signals to achieve on/off control, 2 steps dimming control, or 3-step dimming control function.

A daylight sensor is also employed to set the threshold at which the motion sensor can be activated. With DIP switch, it is easy and accurate to select suitable detection area, motion hold-time, daylight threshold, stand-by dimming level, as well as stand-by period to fit for each specific installation.

Hytronik sensors for ON/OFF Control




HC005S is the smallest microwave sensor with dip switches in the world.

Ultra compact version

HC009S Standard version

Condominium control. Ambient daylight threshold. Zero-cross relay operation

HC002S. Flush mountinh sensor suitable for ceilings. With integrated day light sensor. 

The settings are adjustable.

The sensors can control any lighting load (fluorescent or LED) up to 400W. Using the IP65 sensor mounting box, these devices can be installed even outdoors




HC009SKD sensor with detachable antenna. More flexibility for installers and

lighting designers

HC501S, with 12Vdc input. It can be customised for 24V and 48Vdc

HC002S. Flush mountinh sensor suitable for ceilings. With integrated day light sensor. 

The settings are adjustable.



Microwave sensor with Integrated LED Driver. ON/OFF & 3 Step Dimming




HC8025 Sensor with integrated and antenna. Maximum LED load 25Watt

microwave-sensor with LED driver for up to 25W

Led load. 3-Step dimming is available with this devide

HC407VDS + HRC-01

With built-in daylight sensor DS02, interactwith daylight, and maintain the Lux level.

DALI Sensors

Digital Addressable Lighting Interface (DALI) is the most precise method of controlling LED lights, with 254 levels of brightness you can achive accurate lighting levels.The DALI Sensor can be integrated in lighting fixtures and luminaires that are part of larger and more complicated DALI System. The sensors can take commandss from a DALI master controllers, it is possible to create a group of up to 64 luminaires with up to 64 microwave-sensors. The main funtions are: switch on/off, or dimmming the assigned group members, and feed back the status to the DALI Controller/Master.

Lighting Applications with Microwave Sensors.

The most typical example is to install the s ensor in fully enclosed lighting fitting. The sensor on its own  achieves a first level of smart lighting control that offers the consumers significant energy savings and security. The combination with 1-10V or DALI dimmable LED Drivers makes an intelligent lighting system ideal for corridors, parking lots, warehouses and offices or even outdoor lighting. 

Outdoor lighting

Using our special box with  ingress protection IP65, the sensors can be installed outdoors in any weather condition. Using a sensor in-the-box, a single LED fitting or a group of fittings are controlled with movement detection. For additional energy savings, the adjustable built-in photocell will operate the lights only at pre-defined lux levels. The IP65 sensor box completely transparent to allow the activation of the photocell by natural day light. 

There is no need to use the PIR sensor and the reasons are explained below:


The old conventional PIR's (infrared motion detectors) are not as accurate as the microwave sensors. Mains disadvantages of PIR

  • It is difficult to set accurately detection range and on/off period
  • They are inactive when they are surrounded by plastic or other materials
  • Last no more than 5 years
  • Very slow response

Why Microwave Sensors are the right solution 

  • They have longe life span of over 50,000 hours
  • Parameters can be set with accuracy
  • Fast response
  • Detect movement through plastic, wood and plasterbord
