PIR Movement Sensor – Fall Alarm for Existing Nurse Call

An infrared motion sensor alerting to movement.

The PIR Motion sensor is a small battery-powered sensor that can be positioned in a variety of ways to alert to movement through a doorway, corridor, next to a bed or over a wider area.

The sensor works using the same infrared technology as the systems used to turn on outdoor lighting. The sensor is positioned pointing towards the area where movement detection is requried. Sensor can be positioned on a wardrobe or wall pointing towards the area next to the bed. When movement is detected in this area the sensor sends the alert through existing call system. 

By adjusting the eyelids over the sensor it is possible to steer the sensor’s beam so that it only detects over

a certain area. The sensor can work in both darkness and light.

 

The ‘eye’ has two eyelids which move to steer the angle of the detection beam. They can be rotated to give a very tight angle or opened up to give a very wide detection field. By choosing the right position for the sensor and setting the angle, any detection setup is possible. The diagram below demonstrates some common configurations.
