Abstract: Ultrasonic waveguide techniques are most familiar to monitor temperatures in the hostile environments. A single waveguide could be used as multiple sensors. In the present work, a thin strip ...
This project implements a soil moisture and temperature sensor using the TI MSP430 microcontroller. The device communicates via Bluetooth Low Energy (BLE) to transmit sensor data to a mobile ...
