Motion Sensor for Nursing Home & Hospital Call Systems
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.
- Impact resistant casing & protective rubber boot – built to last.
- Adjustable sensor angle – narrow beam alongside the bed to a wider area.
- A 30-second timer to allow a carer to leave the room.
- Additional socket for a call bell or floor pressure mat.
- Wall mounting plate included.
- Compatible with any nurse call system.
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 motion detection is required. The 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 an 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.
Turning the sensor on activates a 30-second timer, allowing the carer to exit the room.
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.
Setup 1 is the sensor position detecting movement to the right.
Setup 2 gives a wide detection area across a room or hallway. Positioned at head height on a wall, movement across the whole room is detected.
Setup 3 gives detection below and to the right and
Setup 4 will detect movement in-front of and below the sensor. The beam has a long range of over ten meters. Closing the eyelids totally will stop the sensor from detecting, as will switching the sensor off. Experiment with position and setup for the perfect system.
