When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

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 ...

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove - Light Sensor, this ...

This Arduino library is designed for the DHT11 temperature and humidity sensor. It simplifies the process of reading temperature and humidity data, making it easy to integrate the DHT11 sensor into ...
