German SEKER sensor SEKER model SEKER price

SEKER sensors are used to detect angles. There is a hole in its body that can fit a LEGO axle. When connected to RCX, the angle sensor counts once for every 1/16 rotation of the axle. When rotating in one direction, the count increases; when the direction of rotation changes, the count decreases. The count is related to the initial position of the angle sensor. When initializing the angle sensor, its count value is set to 0. If needed, you can reset it via programming.

SEKER sensor applications

The most widespread application of distance sensors is in mobile phones. Smartphones on the market all contain distance sensors. When a user answers a call, the phone is close to the ear, making accidental operations likely (for example, cheeks puffing out while laughing may easily hang up the call). Therefore, distance sensors are required to monitor the distance in real time. When the distance is too close, the screen automatically turns off to prevent accidental operations. In addition, distance sensors are widely used for measuring mine shaft depth, detecting aircraft altitude, and exploring outdoor environments. With continuous technological development, they also show prominent performance in wearable devices (such as smart belts).

SEKER sensor working principle

When a time-of-flight laser sensor is in operation, it must measure the transmission time with extreme precision because the speed of light is very high. For example, the speed of light is approximately 3´108m/s. To achieve a resolution of 1mm, the electronic circuit of the time-of-flight ranging sensor must be able to distinguish the following extremely short time interval: 0.001m¸(3´108m/s)=3ps. Distinguishing a time interval of 3ps places excessively high demands on electronic technology and is too costly to implement. However, today's affordable time-of-flight laser sensors cleverly avoid this obstacle by using a simple statistical principle, namely the law of averages, to achieve a resolution of 1mm while ensuring response speed.

SEKER sensor industry applications

1) Application in taxi meter testing systems: To further promote energy conservation and emission reduction and address the metrology needs of the electric vehicle industry, the mobile electric taxi meter testing system has been officially launched. The testing device is roughly divided into two parts: a main unit about the size of a password case, placed on the back seat of the car, and a distance sensor attached to the car body. According to reports, the device uses the driving distance measurement method. As the driver drives the car for a certain distance, the testing device and the meter sample synchronously. The entire testing process is expected to be completed in seven to eight minutes. 2) Wide-ranging applications in the automation field: Today, in addition to ultrasonic sensors and standard photoelectric sensors, a new method capable of solving long-distance measurement and inspection tasks has been added to automatic detection and control methods: the time-of-flight laser distance sensor. It provides application flexibility for various scenarios, including the following: (1) Equipment positioning. (2) Measuring the level of material in bags. (3) Measuring the distance to objects and object height on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection scenarios. (7) Aircraft ground clearance monitoring.
