When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...
Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...
One of the latest additions to the extensive range of Baumer sensors is the NexSonic UF300, an ultra-compact 18mm flat ultrasonic sensor with a 3-meter sensing range and ideally suited to ...
Abstract: This paper presents design and implementation of an ultrasonic sensor based walking stick for visually impaired person. An ultrasonic sensor module, HC-SR04 is used for obstacle detection in ...
Abstract: In this paper, ultrasonic sensor based on multimode interference in single-mode–multimode–single-mode optic fiber structure for non-contact displacement measurement is presented and ...
The IM19 is used in conjunction with the UM980 GNSS receiver to provide tilt-compensated Lat/Lon/Alt readings with 1cm accuracy up to 30° tilt angle, and 2cm accuracy up to 60°. Various bits of the ...
Precision sowing requires that the seeds be sown to a sowing depth suitable for seed germination according to the accurate sowing amount and appropriate seed spacing ( Zhai et al., 2014). The ...
