12mm 12528 LDR is a type of photoresistor with a 12mm diameter and the model number GL12528, which changes its resistance based on the intensity of light it is exposed to. The resistance of the component is high in the dark and drops significantly as light increases, making it useful for detecting ambient light levels
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
Transceiver module based on an NRF24L01 allowing a 2.4 GHz wireless connection. This module communicates with an Arduino or compatible microcontroller via the SPI bus.

The Arduino UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family.
The MQ3 analog gas sensor is suitable for detecting alcohol; this sensor can be used in a breathalyzer.
It has high sensitivity to alcohol and low sensitivity to gasoline.
The sensitivity can be adjusted using a potentiometer.
A 5v relay is an automatic switch that is commonly used in an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V.
