Installing our Sensors – (PIR)(WDCRD) Movement and Motion Sensor

Installing our Sensors – (PIR)(WDCRD) Movement and Motion Sensor

In our latest series of blogs we look at ‘Installing our Sensor’. This is the most common enquiry we receive, along with “what is the best way to install my sensors”.

When you buy our sensors you will receive a box with the components ready to set up. You receive the software you’ll need in order to gather and analyse the information you receive. In this series of blogs we will look at how to install our products and how you can best utilise the sensor ranges to gain the information you require. We have already shown you how to set up our Occupancy Sensor (WDCOCC).

For this blog we will turn our attention to our Movement and Motion Sensor (PIR)(WDCRD).

This motion sensor measures when people enter a breakout or meeting room and when they move around it. The primary function is to provide information whether or not the room is in use or not. It will not provide a head count for the room.

Placement and Installation

The Movement and Motion Sensor (PIR)(WDCRD)  is a simple sensor which should be placed on the ceiling of the room in a position which will enable it to pick up any movement within the room. The diagram below (fig.1) explains how best to position the sensor and it should be installed using an articulated bracket (pictured fig.2) so that the position can be change or tweaked for optimal accuracy. The range of the sensor is also indicated on the diagram below.

Imagine your home alarm system and where you place the PIR sensors – this sensor should be used in the same manner.


Installing our Movement and Motion Sensor couldn’t be simpler. Once you have established where the sensors are to be placed you will need 3x AAA Alkaline Batteries, we recommend Industrial by Duracell which should give you around three year’s life before they need changing.  If you would like more information on the best batteries to use for our sensors you can read our blog on the subject.

As you can see from the photograph above (fig. 2) you will need to fix your sensor to the ceiling using an articulated bracket so you can easily adjust the direction of the sensor.

If you are still having difficulty installing your sensors or have a specific question regarding your set up please feel free to email us. You can also follow us on Facebook, Twitter and LinkedIn.
