Abstract: This paper investigates the problem of source localization using signal time-difference-of-arrival (TDOA) measurements in the presence of clock synchronization bias and sensor position ...
The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.
Works with the HC-SR04 ultrasonic sensor in the 3 Pin Mode/4 Pin Mode, the Ping))) ultrasonic sensor in the 3 Pin Mode and the DHT temperature/humidity sensors for getting precise distance values. !
Abstract: Nowadays, the Internet of Things (IoT) plays a significant role in the development of various real-life applications such as smart cities, healthcare, precision agriculture, and industrial ...
