An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...
A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...
In “End of Days,” Chris Jennings recounts how a collision between apocalyptic Christianity and federal overreach led to a deadly standoff in Idaho. By Meghan O’Gieblyn What’s a publisher to do when a ...
Arduino and Seeed have collaborated to produce the Arduino Sensor Kit. Based on the Arduino UNO, the STEM kit is aimed at those getting started with electronics and sensors easier. It contains a Base ...
Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, ...
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: An indirect time-of-flight (iToF) CMOS image sensor (CIS) has been designed with 65-nm pixel-level stacked backside-illuminated (BSI) CIS technology. By using an adaptable tap for ambient ...
Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...
