USER MANUAL

EMDC –ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR

1General description

This user manual describes the functionality of the family of ceiling-mounted motion detec-

tors and light level sensors EMDC.

The EMDC product family consists of the following members:

◼EMDCA using 868.300 MHz radio (main market Europe)

◼EMDCU using 902.875 MHz radio (main market US / Canada)

◼EMDCJ using 928.350 MHz radio (main market Japan)

The term “EMDC” is used throughout this user manual to describe all three variants unless

otherwise noted.

1.1 Basic functionality

EMDC enables the realization of energy harvesting wireless occupancy and light level sensors

for light, building or industrial control systems communicating with the 868.3 MHz (EMDCA),

902.875 MHz (EMDCU) or 928.35 MHz (EMDCJ) versions of the EnOcean radio standard.

EMDC uses a passive infrared (PIR) sensor to detect motion and a dedicated illumination

sensor to measure the amount of ambient light.

EMDC reports periodically (approximately every 2 minutes when no motion is detected, ap-

proximately every 1 minute when motion is detected) the latest motion detection status

(motion detected, or no motion detected). EMDC will report immediately if motion is detected

for the first time after a period without detected motion (e.g. when a person is entering a

room).

EMDC will use EnOcean Equipment Profiles (EEP) of the EnOcean radio standard for the re-

porting of the motion detection status. Depending on the selected EEP, EMDC can additionally

report the measured ambient light level and the measured temperature status.

EMDC is self-supplied via an integrated solar cell which generates the energy required for its

operation. EMDC requires 50 lux illumination for 6 hours per day directly at the solar cell

which typically is equivalent 200 lux for 6 hours per day to at room level. EMDC is fully self-

powered (no batteries required) under these lighting conditions.

For cases where sufficient ambient light is not available, EMDC provides the option to mount

a CR2032 backup battery.

EMDC supports both standard and high security mode as specified by EnOcean Alliance. In

high security mode, radio telegrams transmitted by EMDC are both encrypted and authenti-

cated using AES-128 with a device-unique private key and a sequence counter. This ensures

confidentiality, integrity and authenticity of the transmitted telegrams and prevents telegram

replay (retransmission of previously transmitted telegrams).

Note 1: PIR detection requires that the moving object to be detected is significantly warmer

than its environment. For the case of human motion, this means that the environment needs

to be significantly colder than the human body temperature of 36.5 °C / 98 F.

2Functional description

2.1 EMDC product overview

The energy harvesting ceiling-mounted motion and illumination sensor EMDC from EnOcean

provides wireless motion and illumination sensing functionality without batteries. Power is

provided by a built-in solar cell harvesting available light from the environment.

EMDC transmits sensor data based on the EnOcean radio standard using EnOcean Equipment

Profiles (EEP).

The outer appearance of EMDC is shown in Figure 1 below.

Figure 1 –EMDC external view

USER MANUAL

EMDC –ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR

2.2 Basic functionality

EMDC devices contain a passive infrared sensor that detects changes in the received infrared

radiation which are characteristic for the movement of persons. In addition, EMDC measures

the ambient light level via a dedicated sensor and the temperature using its integrated mi-

crocontroller.

EMDC integrates a solar cell that generates the required energy for its operation from avail-

able ambient light.

The user interface of EMDC consists of one button for simple configuration tasks and one LED

to provide user feedback. Configuration of EMDC parameters is possible via an integrated

NFC (ISO 14443) interface.

EMDC is designed for ceiling mounting. It can be mounted on most ceilings with suitable

screws or mounted on dropped ceilings using wire brackets.

2.3 External product interface

The external product interface consists of the following items:

◼Infrared lens in conjunction with a passive infrared sensor for motion detection

◼Ambient light sensor for light measurement

◼Solar cell can for powering the device in normal lighting conditions

◼User interface. With one button (LRN) and one LED simple configuration and test

◼Internal NFC antenna (not visible) providing access to the NFC configuration

◼Wall mount plate (with opening slot for removal) for product mounting

Figure 2 below shows the location of these items.
