Liquid Level Controller System Without Contact project mainly aims to detect the level of liquid using ultrasonic module. This ultrasonic sensor measure the level of liquid in centimeter by detecting the reflection coming ahead of it. The first pump automatically starts filling the container with water as soon as the level falls below a set point. If the water level goes below the set level the other motor starts pumping out the water from the container. Thus by switching between these motors, the system maintains the water level in the container. The system makes use of PIC microcontroller 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. PIC microcontroller then operates to bring the liquid level to the desired range.
