SCT-013 30A is a Non-invasive AC Current Sensor Transformer. It is a current transformer that can be used to measure AC current up to 100 amperes. This non-invasive current sensor clamped around the supply line can measure a load up to 30 Amps, and allow you to calculate how much current pass through it. It can be useful for building your own energy monitor or for building an over-current protection device for an AC load. SCT-013 30A can be used to detect a current of up to 30A. Simply clip it around the current source that you wish to measure and it will produce a (very) small AC voltage proportional to the current. The cable is terminated on one end with a standard 3.5mm jack (like a headphone jack).
Use this to build your own energy monitor and keep your power usage down, or use it to build an over-current protection device for an AC load. <a href="https://learn.openenergymonitor.org/electricity-monitoring/ct-sensors/interface-with-arduino">Useful information about SCT-013 Current Sensors</a>.

The ESP32-S is a very flexible IOT board that is a significant superset of the popular ESP8266 line. Compared to the ESP8266, it primarily adds significantly more I/O that is very flexible in its functionality as well as Bluetooth. The downside is that being newer, the support is not as extensive as it is for the ESP8266 for some of the unique features such as using the hall effect sensor, IR remote or I2S buses, but items such as CAN bus and capacitive touch are supported in the Arduino IDE.
Besides the IDE, ESP32-S can also be programmed using the Espressif IDF, Microphytoon, LUA and other programming environments.
Compared to the typical AVR processor of the standard Arduino ESP32-S also has a larger 4 MB of Flash memory for program space and runs at clock speeds of 160 MHz and can sometimes optionally be overclocked to 240 MHz and therefore has a very fast processing speed. These can be used as a stand-alone MCU in place of something like an Arduino or it can be used as a peripheral in conjunction with another MCU just to provide WiFi, Bluetooth or other unique capabilities that it has.
The board incorporates 2 push buttons. One is labeled ‘EN‘ which is the Reset button. The other button is labeled ‘IO0‘ which is also called the Boot button. This button is used to download programs to the board.
The ESP32-S chip allows most of the I/O such as the serial ports and I2C to be multiplexed to any of the GPIO pins for flexibility.
Programming the Board
To communicate over USB, the board uses the CP2102 USB to UART bridge chip. If you experience any issues with connecting to the board, you may need to download a driver for this chip.
Drivers can be downloaded at this link: <a href="https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers" target="_blank" rel="noopener noreferrer">https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers</a>

The Arduino Nano FT232 is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
The Nano 3.0 has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1).

The Nano equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano. The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano R3). It has more or less the same functionality of the Arduino Uno but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
The Nano can be power via the mini-USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
The size of Nano V3.0 with CH340 Chip is only 43 mm x 18 mm; it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed and 32kB of flash memory.
