The Pixel 4 is the only handset in the world to feature a radar chip that can detect hand gestures and movement. However, the Soli-powered Motion Sense is more of a gimmick than a must-have ...

A lot of projects we see around here are built not just because they can be built, but because there’s no other option available. Necessity is the mother of invention, as they say. And for [Jeff ...

An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...

Includes the Servo library #include <Servo.h>. // Defines Tirg and Echo pins of the Ultrasonic Sensor const int trigPin = 10; const int echoPin = 11; // Variables for the duration and the distance ...

To tackle data sparsity and noise of RADAR detections, we propose a deep learning-based Inverse Sensor Model (ISM) to learn the mapping from sparse RADAR detections to polar measurement grids.

However, the existing sensors are either not practical for wireless implementation, does not have enough accuracy, or are not cost-effective. This paper presents a multi-function interferometric radar ...
