Things That are used on our project Arduino ESP32 Hepa Filter MQ135 MQ7 Oximeter Sensor OLED Screen Chargeable Batteries MQ135 - Requires 3 Pins(VCC, GND, Analog) Pulse Oximeter - Required 4 pins(SCL, SDA, VIN, GND) volvo is truck Manufacturing company globally.  program to display different types of data on OLED display by using ESP32. program to calculate aqi using mq135 and MQ7. Also, send a message or WhatsApp notification to joined numbers. only our sensors are capable to detect the air quality inside the cabin which saves energy and also give long life to our hepa filter and batteries. At, every hour if buzzer alert to driver then it difficult for the driver to drive and also distract. if he is not feeling well then he can check his heart rate and blood levels to clarify his health issues. if the value is below to the requirements then it allert driver and fleet management to replace him with other drivers. so he gets a doctor checkup and treatment.

Complemetry Metal Oxide Semiconductor(CMOS) Complementry Transistor Network 1. Pull UP : P transistor 2. Pull Down : N Transistor An NMOS and PMOS make up an inverter. CMOS is used as Transmission Gates

Pure Silicon or Germanium are rarely used as semiconductors. Practically usable semiconductors must have controlled quantity of impurities added to them. Addition of impurity will change the conductor ability and it acts as a semiconductor. The process of adding an impurity to an intrinsic or pure material is called doping and the impurity is called a dopant. After doping, an intrinsic material becomes an extrinsic material. Practically only after doping these materials become usable Effect of Doping on N-type Material The effect of doping on an N-type material is as follows − On addition of Arsenic to pure Silicon, the crystal becomes an N-type material. Arsenic atom has additional electrons or negative charges that do not take part in the process of covalent bonding. These impurities give up or donate, one electron to the crystal and they are referred to as donor impurities. An N-type material has extra or free electrons than an intrinsic material. An N-type material is not negativel...

A computer system that is integrated into a bigger device or system to carry out a specific task is known as an embedded system. It is a hybrid of hardware and software created to carry out a specific task, frequently under the restrictions of real-time computing. From basic gadgets like a microwave oven to complicated systems like aeroplanes and medical equipment, embedded systems are included in a wide variety of products. Embedded systems are often built to work in a particular context and have constrained resources, such as memory and computing power. They frequently employ real-time operating systems, specific programming languages, and specialised input/output and communication interfaces. Embedded systems are used for the specific task. They are made from microcontrollers which is the brain of the system. It is a Microcontroller - based system that is designed to control a task or range of tasks and is not meant to programmed by the end user. A microcontroller has on chip RAM, o...

                                BJT BJT is NPN or PNP. BJT is a current controlled device. The temperature coefficient of BJT is negative. The input resistance of BJT is low. The switching speed of BJT is slower. BJT is not expensive. The current output of BJT can be controlled through the input base current. it is used for the low current application.                                MOSFET MOSFET is P-type or N-type. MOSFET is a voltage controlled device. The temperature coefficient of MOSFET is positive. The input resistance of MOSFET is high. The switching speed of MOSFET is higher. BJT is not expensive. The current output of BJT can be controlled through the input base current. it is used for the low current application.

 Qus. Why should I hire you? Qus. You are not selected in this company now what you can do? (QUS). what you do when company rejected you? (ANS). i ask the shortcomings that interviewer will see in me and i try for the next with much preparation so next time i will surely be a part of your company. yes, i can relocate to work with new collegues, new exposure and visiting new place. after some time i call parents to live with me and  my weakness is workholic. when i started work then i skip the lunch or dinner to complete the work. i am very helpful person but due to this i am not able to complete my own task. after realizing it i startred selfish behavior to complete my own task. Previous times when I write assignment given to me for that I skip the dinner. I believe in permanency in work. So, if I work with the same energy and concentration then this company will also offer me same or high salary. So, I give best to this company to grow my life with this company. What are the ...

ESP32 is a development kit which has inbuilt WiFi and Bluetooth technology. It is very helpful in making internet of things projects We are going to use thonny software to program the ESP32 kit. 

Very Large Scale Integration are most important to grow in the field of integrated circuits and chip manufacturing. The tools that we used to design a chip. VHDL(Very high speed Integrated circuits hardware description language) is used to design a working model of chip. The various stages -: 1. Small scale integration 2. Medium scale integration 3. Large Scale Integration 4. Very Large Scale Integration 5. Micro technology To learn this core field you have a very strong knowledge about different types of logic gates, sequential circuits and combinational circuits. This all comes in the core subjects i.e Digital Electronics. Which helps you to get a particular chip which performs various calculation. There is a huge demand of chip in the world. So, this is basically a growing industry where you can make a good career. This core field is basically related to electronic and Communication engineer and electrical and electronic engineer.
