The kit Simple water level indicator The use of transistor is very easy to build four led for indication of the levels in sequence and a buzzer is used to indicate the overflow condition. For the use of the circuits attach the six cables Or probes in the water tank to your desired level. The LED will illuminate when the water touches these six wires and this will indicate that the water level has reached the desired level.
Level the water in a tank and check a pump motor as needed. The circuit designed for the digital water level indicator of the tank above with an LCD display is to show the up / down water level in the tank. A relay is used to power a motor off (proving like a lamp here) every time the tank exceeds its maximum level ie it automatically shuts off the engine (which proves like a lamp here). The sensor ground terminal must be kept at the bottom of the vessel (tank).
The power supply consists of a 230 / 12V reduction transformer, which lowers the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The undulations are removed using a capacitive filter, and then regulated to + 5V using a 7805 voltage regulator, which is required for the operation of different IC and components.
In addition, the project can be improved by interconnecting it with a buzzer to alert when the water level falls below a minimum level and then a GSM modem can be interconnected so that the readings can be sent remotely to a mobile phone, where the readings Have a crucial role.
