/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* Ek realy Jo float megnetic sensor high ho tab */
    /* realy on rahe or sensor low hone ke 15 second bad */
    /* realy off ho jaye or 30 minutes ke baad automatic */
    /* realy on ho jaye jab realy on ho uske baad sensor */
    /* ke according realy work kare */
