Loading cement sacks into trucks requires precise counting for traceability, yet manual methods are error-prone and often ...
The analog value from the sensor is converted to distance using either a polynomial fit function up to fifth order or a power fit function. By default, this library is set to use polynomial ...
The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...
The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...
Abstract: Occupancy awareness is important for appliance control, ubiquitous computing, and analytics for enterprize real estate. In this paper, a low-cost, battery-powered, wireless occupancy ...
A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...
Abstract: This work presents a low-cost sensor and machine learning methods approach for plastic recognition in daily used objects. The sensor is a multi-spectral near-infrared sensor capable of ...
