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 ...

Abstract: The localization of sound sources in urban environments is a challenging task and the self-position and self-orientation of the individual sensor nodes can usually not be assumed to be ...

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 ...
