Motion sensors are an important component of any security system. For high-performance requirements in motion sensing, TDK offers MEMS products, such as accelerometers and gyroscopes used in navigation, motion tracking and motion control, as well as optical stabilization. A motion sensor, or motion detector, is an electronic device that uses a sensor to detect nearby people or objects. Motion-based devices detect and track an object's motion in three-dimensional space enabling key functions in many consumer electronic devices including mobile, wearable, Smart Home, and automotive and industrial devices. Magnetic-field sensors based on Hall-sensor or TMR technology can be found in almost any machine that needs to measure position, linear or rotational movement or even current. Pressure sensors are used in a wide range of applications in automotive and industrial electronics, medical engineering, and environmental technology.
Temperature sensors and sensor systems are used to regulate the temperature of refrigerators and air-conditioning systems or to measure the temperature of operating fluids in motor vehicles, for example. Precise current sensors are indispensable for intelligent power in electric vehicles and smart grids. TDK's complete range of sensors, marketed under the product brands TDK, EPCOS, InvenSense, Micronas and Tronics includes temperature sensors, pressure sensors, angle sensors, current sensors. Over the years, with the innovative use of sensors and motor controllers, vacuum cleaning robots have become much smarter, overcoming these issues. And, as their dust box is comparatively small to a regular vacuum cleaner, if full, they could be sweeping but not collecting anything up. Often, they would unwittingly become trapped or run out of charge mid-sweep. To illustrate how various sensor technologies from TDK’s SmartSensor family can be applied in service robots, this article focuses on a robotic vacuum cleaner (RVC).Įarly versions of robotic vacuums had very little intelligence, randomly bumping their way around the home and sometimes missing areas as they did not know where they had been. Regardless of their application, they need to sense changes in their surroundings in real-time to ensure safety while providing a positive user experience. For the most effective coverage, outdoor motion sensor lights should cover between 75 and 100 square feet of the area when lit. Service robots play an increasingly vital role in society, from transportation and warehouse logistics to home entertainment and security. Outdoor motion sensor lights can cover a wide range of spaces some may only illuminate a small space, such as a stairwell, while others have a much wider range, illuminating larger spaces like your backyard.
