Getting started guide & review of the SONOFF Dongle Plus MG24 Zigbee adapter with Home Assistant, AirGuard TH monitor, and ...
Abstract: A new analytical method for 3-D target localization based on a four-element ultrasonic sensor array is proposed. In the sensor array, with the consideration of good real-time performance, ...
Abstract: The computational and memory resources of wireless sensor nodes are typically very limited, as the employed low-energy microcontrollers provide only hardware support for 16 bit integer ...
The HC-SR04 ultrasonic sensor is an affordable and super-popular sensor that measures the distance between itself and an object located in front of the sensor. Very simple to use, it returns the ...
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 ...
