IOT BASED SMART STREET LIGHT SYSTEM
Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without warring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

The ENC28J60 Ethernet Module is a board which contains an Ethernet port and converts Ethernet input into SPI. The board is based on Microchip’s ENC28J60 integrated circuit and it can be used to provide internet connectivity to microcontroller systems like Arduino boards over Ethernet.
One of the most useful things you can do with an Arduino is control higher voltage (120- 240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay.
The meter which is used for measuring the power of three phase supply is known as the three phase energy meter. The three phase meter is constructed by connecting the two single phase meter through the shaft. The total energy is the sum of the reading of both the elements.
A GSM Module is basically a GSM Modem Â (like SIM 800) connected to a PCB with different types of output taken from the board – say TTL Output (for Arduino, 8051 and other microcontrollers) and RS232 Output to interface directly with a PC. The board will also have pins or provisions to attach mic and speaker, to take out +5V or other values of power and ground connections. These type of provisions vary with different modules.
3 PHASE CONTECTOR
As contactors are used for high-current load applications they are designed to control and reduce the arc produced when the heavy motor currents are interrupted. Â Other than the low current contacts, they are also setup with Normally Open contacts. Â These are devices which handle more than 20 Amperes current and over 100 Kilo Watts power. The contactor has an AC/DC supply driven coil input..
The TIMER is a 7 day timer that allows up to 8 on/off functions per day. It comes in 4 specific voltages: 12VDC, 24VAC/VDC, 120VAC and 240VAC. First, please check that you have the correct voltage for the application. The specified voltage is for the timer only. The output to your timed device goes through the contacts of the output relay which is rated to a maximum of 16a resistive and 8a inductive at 250VAC, 20 amps resistive at 125VAC and 16a at 30VDC.
