Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Non-contact proximity sensors can improve the ruggedness of manufacturing operations, such as metal component assembly, by replacing delicate mechanical switches. Sensor selection for these ...

I’m working on a project involving the need to precisely move a tool based on the measured distance to an object. Okay, yeah, it’s a CNC mill. Anyway, I’d heard of time of fight sensors and decided to ...

Electronic enthusiasts that need to measure angles on their robotic arm or other projects may be interested in a new proximity sensor that has been created by William Moore called the Protractor. The ...

iPhone sensors like accelerometers and LiDAR do way more than you think-from measuring spices to hands-free cooking and identifying mystery ingredients.

Today, most modern Android devices are kitted out with a bunch of sensors. You can use this information in lots of different ways – whether it’s monitoring light levels so your application can ...

Ensuring safe social distancing is one piece of the puzzle for workers in the COVID-19 age. Ultrasonic range-finding sensors can measure the distance between workers with centimeter accuracy and alert ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

Last year we took a look at Postifier, a device that sits in a mailbox patiently awaiting any deliveries and alerting users on their smartphone when something arrives. Because Postifier relied on ...

STMicroelectronics has created a time-of-flight distance sensor for industrial use. VL53L4ED works over -40 to +105°C and in high ambient light, and provides “provides distance measurement to objects ...
