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. !

In many applications, harsh ambient conditions present a significant challenge for sensor technology. In such cases, ultrasonic sensors that are largely unaffected by physical influences become ...

Abstract: To provide an efficient solution to the difficulty in navigation faced by the visually impaired, this paper presents a device built on the principle of object detection. This model utilizes ...
