Bluetooth-Controlled Water Level Monitoring and Pump Control System with Arduino and Ultrasonic Sensors
View and Edit Project In Cirkit Designer
Circuit Documentation
Summary
The circuit in question appears to be a control system that utilizes an Arduino Uno R3 as the central processing unit, interfacing with various sensors and modules to perform specific tasks. The HC-05 Bluetooth Module allows for wireless communication, while the HC-SR04 Ultrasonic Sensors are likely used for distance measurement or object detection. A 1-Channel Relay and a Relay Module are included for controlling higher power devices, such as the Water Pump, which is also part of the circuit. A 12V Battery provides power, regulated to the necessary voltage by a Voltage Regulator. The circuit also includes several components labeled as "orifice" and "hpv," which are not standard electronic components and may represent placeholders or custom parts specific to the application.
