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 ...
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: 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 ...
Easy-to-use interface for configuring and reading radar data. Supports both single and multi-target detection modes. Works with Arduino-compatible board that has a separate hardware UART.
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 ...
