Motion detectors and modules
Motion detectors and modules
Unlike passive infrared motion detectors, which only register objects with a temperature difference to the background, radar motion detector modules react to all movements towards the sensor. The motion sensitivity is extremely high, detecting even the slightest movements, almost to the point of standstill. The radar motion detector module delivers an unamplified mixer signal that must be processed in a subsequent amplifier circuit before it can be evaluated by a comparator or microcontroller.
Despite its compact dimensions, the PIR SMD module has performance features that guarantee universal applicability. For example, the sensitivity of the passive infrared motion detector (PIR), which is designed for 12 metres as standard, can be individually adjusted to four different ranges (4 metres, 5 metres, 6 metres and 8 metres). The window comparator integrated on the module delivers a digital switching signal when motion is detected, which is TTL and CMOS compatible and can be further processed by a microcontroller or timer, for example. The PIR module also has an analogue output.
Yes, customised designs are available on request. Please note that due to the planning and implementation costs involved, we can only produce customised designs for orders with a minimum value of €500.00.
A PIR motion detector reacts to the heat radiation emitted by moving bodies. It offers adjustable ranges of up to 12 metres (depending on the product).
Yes, radar motion detectors use microwaves, usually in the 5.8 GHz or 24 GHz frequency range.
Radar motion detectors used in households, security technology or lighting are fundamentally safe. The emitted power is very low (often less than 1 mW) and is well below the limits for radiation that is harmful to health.
