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 ...
The Smart SMS Alert System using Seeed Studio Xiao ESP32 is one of the compact IoT projects that uses an HC-SR04 ultrasonic sensor to detect nearby movement. The system acts like a motion detector ...
This MAX31850 library is not a full featured library for the MAX31850 family. The MAX31850/1 is a Cold-Junction Compensated, 1-Wire Thermocouple-to-Digital Converter. The MAX31850/1 supports K-, J-, N ...
Phlux Technology Aura family of sensors are available in 30µm, 80µm and 200µm versions, and are 12X more sensitive than conventional InGaAs APDs extending the range and accuracy of IR systems by up to ...
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 ...
Abstract: In this paper, we propose a human gesture recognition algorithm using impulse radio ultra-wideband (IR-UWB) radar. The radar signal is transmitted into a three dimensional space, however, ...
