Abstract

A PIR detector 10 incorporated into a three pin mains electrical plug or plug adapter that fits into a conventional mains plug socket. When the PIR detector senses movement, it switches on any electrical appliance that is connected to it. The user has the options of adjustable time delays or a remote switch is provided, to allow the user to switch the device on and off without triggering the electrical appliance to be switched on.

Description

SECURITY DEVICE This invention relates to a PIR security device Passive
Infra Red (PIR) detection devices are well known security devices which detect the movement of warm objects, including people. The PIR sensors are normally connected to relatively expensive alarm systems.
According to the present invention there is a three pin mains electric plug or plug adapter, that fits into any conventional mains electrical socket, with a PIR detector incorporated into it. When the PIR detector senses movement, it switches on the electrical appliance that is connected to it.
Figure 1 illustrates an example of how the security device could look Figure 2 shows a side view of the security device; and Figure 3 shows a view from the side of the security device with the three pins on One example of the device is a mains plug with a PIR detector 10 incorporated into it as shown in Fig. 1. The user would wire the plug onto the electrical cable 16 of their chosen electrical appliance in a similar way as they would to a standard plug. An alternative would be to have a PIR detector incorporated into a mains plug adapter.
Before plugging in the device or switching the power on, the settings can be adjusted to suit the user personal requirements. These settings may include a leaving-time delay 12, an entering-time delay 13, a light level sensor adjustment 14, and function options 15, as shown in Fig. 3. Once it is switched to a PIR function and the power to the plug is switched on, the user has their set amount of time to get out of range of the detector, without it being activated. When the PIR detector senses movement, it waits for the entering-time delay period to elapse before switching on the electrical appliance, there by allowing the user time to switch the device off first. The light level sensor 11, shown in Fig. 1, is normally used when the device is connected to a light so that it will only switch it on at a set level of darkness. The device could be used as an alarm or just to switch on electrical appliances when someone enters the area detectable by the PIR detector.
Another example is to also incorporate an extra function for the alarm. A signal may be sent to a camera pointing at the PIR detection area to take a photo, or to other types of alarm device. The signal may be sent by RF, infra red, microwaves, ultrasonic, an encoded buzzer signal, a wire, or the camera may be physically connected to the device.
A further example is to provide a remote switch, to switch the security device on and off without having to go into the range of the PIR detector.

Claims (8)

1. A security device comprising of a PIR detector built into a three pin mains electrical plug that fits into a conventional mains plug socket. When the PIR detector senses movement it switches on any electrical appliance that is connected to it.
2. A security device as claimed in Claim 1, wherein the plug could be a plug adapter with one or more sockets leading off it which can be switched on and off by the PIR detector.
3. A security device as claimed in Claim 1 or Claim 2, wherein there is a time delay once the device is switched on
4. A security device as claimed in any preceding claim, wherein there is a time delay once the PIR detector senses movement, before it switches the electrical appliance on
5. A security device as claimed in any preceding claim, wherein there is a light level sensor so that the device will only switch on the electrical appliance at a set level of darkness.
6. A security device as claimed in any preceding claim, wherein there is a means of sending a signal to activate another alarm device.
7. A security device as claimed in any preceding claim, wherein a remote switch is provided to switch the device on and off.
8. A security device as claimed in any preceding claims, wherein the device could also be used for non-security applications.
