Motion/brightness sensors
Motion sensors and brightness sensors
In general, our RSM series radar sensors and the B+B brightness sensor can be included in this category.
Unlike passive infrared sensors (PIR), radar sensors react to all movements in the direction of the sensor. The motion sensitivity is extremely high, so that even slight movements (almost to a standstill) are detected. The radar sensor therefore delivers an unamplified mixer signal (VCO oscillator / FMCK/FSK suitable), which must be processed in a subsequent amplifier circuit before it can be evaluated by a comparator or microcontroller. These components make the radar sensor suitable for detecting movement, speed, direction of movement, presence and distance.
Our B+B brightness sensor is used to measure illuminance. This measurement is performed by a precise and long-term stable photodiode, so that the output signal is generated by state-of-the-art sensor technology with an ASIC. In addition, three-point calibration enables us to guarantee high accuracy across the entire measuring range.
Furthermore, this brightness sensor can be operated with either DC or AC supply voltage. This makes the product suitable for use in building technology, automation technology and agriculture, among other areas.
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.
Wall mounts for the B+B rain detector and the B+B brightness sensor can be purchased in our online shop.
Our brightness sensors have an accuracy of <±10% (with vertical light incidence).
The dimensions of the brightness sensor are as follows: (LxWxH) 65 x 59 x 50 mm.
Our brightness sensors are housed in a high-quality plastic casing with IP protection class IP 65.
Passive infrared sensors (PIR) detect heat radiation emitted by moving objects within their detection range by sensing changes in the infrared spectrum. Radar sensors, on the other hand, emit electromagnetic waves and detect the reflection of these waves from objects to detect movement. Radar sensors are often better at detecting movements that are directly approaching the sensor than PIR sensors.
