The project is designed to detect the level of liquid by using an ultrasonic module. The ultrasonic sensor measures the range of liquid level (in cm) by detecting the reflection coming ahead of it. If the measure of the level falls below a set point the first pump automatically starts adding water to the container. If it goes above set level , it starts the other motor that pumps out water of the container. This way it brings the water to desired level by switching between motors.
The project uses a microcontroller whose serial port is interfaced with this ultrasonic module. The Tx sensor sends the ultrasonic signal reflected from the level and is received by the ultrasonic Rx sensor. These signals are then sent to microcontroller that initiates the relay to switch the pumps on or off. The user may check the current liquid level by setting system to normal mode. Then user may switch to setting mode to set liquid level to desired level. Microcontroller then operates the motors to bring liquid level to the desired range.
