This water-level indicator uses a 7-segment display, instead of LEDs, to indicate the water level (low, half and full) in the tank. Moreover, a buzzer is used to alert you of water overflowing from the tank. The circuit shows the water level by displaying L, H and F for low, half and full, respectively. The circuit uses five sensors to sense the different water levels in the tank. Sensor A is connected to the negative terminal (GND) of the power supply. The other four sensors (B through E) are connected to the inputs of NOT gate IC 7404. When ....etc

Water Level Indicator With Alarm


Here is a simple, versatile circuit
which indicates the level of
water in a tank. This circuit produces
alarm when water level is below
the lowest level L1 and also when water
just touches the highest level L12. The
circuit is designed to display 12 different
levels. However, these display levels
can be increased or decreased depending
upon the level resolution required. This
can be done by increasing or decreasing
the numb ....etc

Abstract
A Labview and internet based water level control
system is developed, which enables the students, who
study automatic control, the deeper understanding of
the control theory and the real experiences on control
system design and implementation. The system will
enable the students to do the experiment in their free
time through internet with a remote computer. The
system is of low cost and can also save the course hours
for experimentation.

AUTOMATIC WATER LEVEL INDICATOR


INTRODUCTION:
Generally most houses and buildings have two water tanks, one situated on the roof and another one on the ground or sometimes underground. The received water supply is allowed to fill the lower tank first, and a water pump motor is then switched ON manually so that the water from the lower tank is pumped and shifted into the upper tank on the roof. Once the water from the lower tank is completely transferred into ....etc

Choosing a Microcontroller
 As it provides on chip microprocessor, RAM, ROM, Parallel I/O port, Serial I/O port etc. hence its cost is less, size is less, power consumption is less and speed is more.
 Software development tools like assembler, C compilers etc are easily available and are easy to upgrade.
