As people are getting smarter so are the things. While the thought comes up for Smart cities there is a requirement for Smart waste management. The idea of Smart Dustbin is for the Smart buildings, Colleges, Hospitals and Bus stands. The Smart Dustbin thus thought is an improvement of normal dustbin by elevating it to be smart using sensors and logics. Smart dustbins is a new idea of implementation which makes a normal dustbin into smart using ultrasonic sensors for garbage level detection, IR sensor-1 for human hand detection, and user can monitor the dust level of the bin using LCD display. User can get the alert intimation if the dust bin is full through BLUETOOTH. Servo motor for automatic door open and close of the bin. The smart street light IR snsor-2 for vehicle detection, LDR for day/night sensor. High power LEDs for street lights. Data transmitting between two sections using Lora technology. The main controlling device is Arduino, PIC Microcontroller. The microcontrollers used in the project is programmed using Embedded C language.  

Garbage system:

The main controlling device of the whole system is an arduino microcontroller.SR04, Bluetooth, LCD display, Servo motor and IR SENSOR is interfaced to the arduino micro controller. The arduino microcontroller continuously read the data from sensors. When the IR SENSOR detect the hand then data is fed to the arduino. The arduino opens the door of the bin with the help of servo motor. The arduino microcontroller monitors the dust levels on LCD display with the help of SR04 SENSOR and sends the alert intimation through Bluetooth when the dust bin is full with dust.

Automatic Street light system

The project aims in designing an efficient automatic intensity control of street lights in night time using LDR, IR sensor. Our high power LED based street light controlling system is the result of this idea. This was designed with a vehicle detecting sensor using IR which is capable of sensing the arrival of a vehicle. If there is no vehicle on road, the lights will glow with low intensity. If the vehicle presence on the road the lights will glow with high intensity. This data is fed to the arduino microcontroller then Arduino transmits this data to the street light section through LoRa transmitter and this data received by LoRa receiver and process as this to the PIC Microcontroller and then microcontroller switches on the street lights.

The major features of this project are:

1. Different sensors used to know the status of the dustbin.
2. Intensity control of streetlight.
