If you are using the PIR Transmitter, your options for angling the device are limited. This is due to only Velcro pads being provided to stick the transmitter to the wall. This might miss the area your are hoping to monitor with the transmitter.
By purchasing a PIR Stand for the MPPL PIR Motion Detector, you are widely opening your options.
Features of the PIR Stand for the MPPL PIR Motion Detector
The stand is designed to be free-standing. This means your PIR Transmitter does not need to be mounted onto the wall, but can be positioned wherever is ideal - on a coffee table, for example. Without attaching it to the wall, there is no concern over damaging paintwork or wallpaper either, as the Velcro dots used for attachment can cause problems with this.
