Watmonitor (Water level monitor) works as central web interface for storing data from sensor nodes. Data were shown to user at dashboard, graphs, tables. Watmonitor project consists of a central web ...

A real-time environment monitoring system using an ultrasonic sensor to detect distance changes and trigger proportional visual/auditory alerts. The system leverages LEDs (red/yellow/green), a motor, ...

This project simulates a 2D LiDAR system using SR04 ultrasonic sensors mounted on a stepper motor. The system is controlled by an Arduino UNO (Elegoo R3) and scans the surroundings, sending distance ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...
