2. The difference between Motion & Occupancy Sensors

  • Motion Sensors respond to Walking or Standing Movements. Occupancy sensors can detect fine movements in a sit down position. Motions rendered by people talking on phone, mouse clicks, laptop work can be sensed by a true occupancy sensor but not by an ordinary motion sensor
  • Motion sensing is normally used in toilets, corridors, parking areas, basements and other applications where the movement is always in an upright standing or walking condition. Occupancy sensors are always used for Office cabins, laboratories, libraries, design studios where the occupant is normally seated and the level of motion is severely restricted.
  • Motion sensors should normally be 50% cheaper than a True and Genuine Occupancy Sensors.
  • In a True occupancy sensor, the movement pattern schematic should specifically state finer movement areas and larger movement areas. Whereas the schematic pertaining to a motion sensor will only show a single movement area.
  • A motion sensor uses either PIR or High Frequency Technology where as a TRUE occupancy sensor will always use the PIR Technology only. Mischievously some suppliers offer a combination of both PIR and HF in a single module and qualify it as a OCCUPANCY SENSOR.
  • For a PIR based motion sensor the module should contain anywhere between 1 to 3 pyro detectors whereas a True Occupancy Sensor will always contain 3 or more pyro detectors.
  • A Motion sensor monitors the Lux level only once at the time of initial sensing but a TRUE occupancy sensor regularly monitors the ambient lux levels and turns on or off the lighting loads based on the prevailing levels.

3. Schematic For Occupancy Sensor Area in RED Sensor picks up only walking motion Area in Yellow Sensor picks up motion in seated position 4. TYPES OF SENSORS DALI Sensors for dimming and scene control Analogue Sensors for dimming control 24VDC Sensors for Building management [BMS] Acoustic Sensors for cabins, labs, Class Rooms Dual Channel Sensors for simultaneous HVAC and Lighting control Wall Switches [single gang design] for fitment in switch boxes ideal for small sized cabins. Can handle single or dual circuits simultaneously. Elimination of wiring Solar Based wireless sensors with chargeable battery. Based on 868 MHz frequency and the patented ENOCEAN Technology. High Bay sensors for warehouses, sports halls, arenas. These can be mounted at ceiling heights of 10 to 15 meters. Long Range sensors for sensing diameters of 24 meters or more. Suitable for Car Parks Sensors that work on a Master & Slave format. Ideal for car parks, long corridors, stairways, basements etc 5. PIR Sensor Technology 6. Pyro Detection for PIR Sensors Price increases as the detection area increases Price increases as the number of pyro detector increases 7. High Frequency sensor Technology

  • Fig. Shows the principle of operation of HF sensor.
  • A sensor with transmitter and receiver
  • The transmitter of the high frequency module sends electromagnetic
  • waves and receives the echo reflected by walls and objects.
  • Echo on OccupancyConstant wave Echo without Occupancy

COMMON AREAS OF APPLICATION WITH BENCHMARK SAVINGS Data Source: Madison Gas & Electric Co www.mge.com 10. What Customers probably dont know about Sensors

  • Whether the sensor is tropicalized for Indian Power Conditions and Gen-set operations
  • Whether or not they are comparing similar features of sensors offered by different vendors
  • Whether a sensor is actually required for an application
  • Whether the vendor has done a Data logging exercise for determining the occupancy pattern and payback
  • Whether the vendor has conducted a site survey to determine the actual requirement
  • Whether the sensor reacts adversely to a high harmonic infested circuit
  • Whether the sensor reacts adversely to mobile phones or radio handsets.
  • Whether the sensor has a robust algorithm for reset management.
  • Whether the sensor switches the loads at the zero cross over of a sinusoidal wave form
  • What is the life cycle of the electromechanical relay or solid state switching device in the sensor
  • Whether the sensor is suitably rated for ingress protection [IP] in consonance with the application
  • How does the sensor reacts adversely when placed in close proximity to the lighting loads
  • Does it have a Dead Time Zone feature in the algorithm.
  • Does it have a built in redundancy for obviating false trigger situations
  • Does it serve the required purpose when the time delay is kept to its minimum setting and not maximum setting
  • Whether the sensor is vandal proofed.
  • Whether the faulty sensor can be replaced without dismounting the chassis. Simply speaking is it easy to diagnose and rectify the fault.
  • Whether the vendor is supplying a motion sensor in place of an occupancy sensor
  • Whether a manual bypass facility is available in case of any fault.
  • Whether the sensor has adequate protection or shields against unsolicited movement e.g. ceiling fans, HVAC draughts, open windows, motion across glass walls etc.
  • Can the sensor chassis be installed at the time of the electrification without exposing the PCB and electronics to the site conditions
  • Does it conform to a set of internationally accepted quality standards
