Story

in india seasonal rivers don't have water all over the year and what happen people use to go inside river when the level is not very high or may be the dams store the water so the level is not very high usually. so when the water is released the level increased or whenever their is rainfall at mountain the level of water increases and the far away people don't know about it.

so i have made a water level indicator which will indicate via SMS.

here i have made three level in the bottle to demonstrate it and whenever the water reach that level the indication is made on the LED and also via SMS to particular phone number.

Step 1 - Creating different levels

Here i am using bottle for an example

i have created three levels which have wires at that level and at the bottom low voltage 5v supply is given which will be passed onto the level wire when water is inserted and reach the level.

Step 2 - Circuit Designing

Power supply requirement: it can be battery based if you want to make your system mobile for installation in remote areas and be recharged via solar pannel if you are using rechargeable battery.

i have designed an on board power supply using 12 - 0- 12 transformer, diode in4007, capacitor 1000uf and regulator 7805.

the power supply requirement of controller section is 5v and that of GSM is 12v.

in controller section we use 40 pin ic base and design the circuit for reset section and crystal section.

the value of crystal used is 11.0592mhz to easily maintain the baud rate for GSM modem to 9600 hz

5v Vcc is provided to pin 40 of microcontroller and ground is provided to pin 20.

next Led will be interfaced with the microcontroller for indication of the levels.

to interface the GSM modem firstly the power supply of 12 v is provided and then the serial receiver pin of the Gsm is interfaced with serial transmit pin of microcontroller and vice versa.

The Sim should be inserted in modem for availing the SMS feature
