BLOCK DIAGRAM DESCRIPTION
• Transformer, rectifier and regulator is used to provide power supply
• Light is sensed by using LDR and control the lamp through relay
• Motion is detected by using PIR and security is provided by making alarm through buzzer.
• Temperature & humidity can be sensed and can be used to control fan using DHT11..

• Water level in tanks or even having a check on floods can be done using ultrasonic sensor.
• Plant watering is made simpler in this project by measuring moisture content on soil and watering accordingly.
