The flood detection tool uses the HC-SR04 sensor made specifically to detect the water level in the river. This tool is a series of simple tools that utilize the esp32 microcontroller and media monitoring in real time via a smartphone. The flood detection tool using the HC-SR04 sensor consists of a tool frame made of […]
Biological components including cells, proteins, and nucleic acids have been studied by using biological sensors. All compounds in the organisms have sensors with identical mechanical sensors. Most of these sensors are specific cells which are sensitive to physical characteristics of outside environment including light, motion, temperature, magnetic-field, gravity, moisture, vibration, pressure, electrical fields, and sound.
