Hardwares & Sensors

Arduino

Arduino is an open source electronic system that is easy to use. It can be used as a both hardware and software. Arduino boards that can also read inputs from the sensors that inputs are used to turn on sensors, activating a motor and also the turning on LED etc.  We can send instruction to arduino board what we want to do to with our experiment. To doing this we need arduino programming language based software that can be easily installed in our Windows and we can also use arduino software that is based on processing which is simply known as IDE.

ESP32

ESP32 is a low power system microcontroller  with integrated Wi-Fi on a the chip. It is Designed for cell phones, Connecting to wifi, wearable hardware and many kinds of IoT applications, platforms ESP32 accomplishes ultra-low force utilization with a mix of a few kinds of restrictive programming. ESP32 additionally incorporates cutting edge highlights, for example, fine-grained clock gating, different force modes and dynamic force scaling. It can work good in mechanical conditions, with a working temperature in the range from – 40°C to +125°C. Fueled by cutting edge alignment hardware. In The first step we will add WiFi.h library. That will allow to connect to a any WiFi network in a every area, amongst many other functionalities. Next step is to declare global variables WiFi network credentials, first is name (SSID) and the password. In the main line of our arrangement work, we will open a sequential association, so we can yield the after effects of our program to the Arduino IDE sequential screen. To do as such, we simply need to call the start of the Serial article, going as info the baud pace of the association, in bits every second. We will use 115200 as per our requirement   for the speed of the connection. After writing the full code in arduino then  compile & run the code to ESP32. ESP32 provide is very easy  functionality of connecting to internet. ESP32 itself connect to a WiFi network as per availability.

Ad8232

Ad8232 is sensor its functional board used to measure the electrical activity of the heart. This electrical development can be diagrammed as an ECG or Electrocardiogram and yield as a basic examining. The AD8232 Single Lead Heart Rate Monitor goes about as an activity amp to help obtain a sensible sign from the PR and QT Intervals adequately of ECG signal.  The AD8232 is a fused sign embellishment block for ECG and other bio potential estimation applications.

DHT11

The DHT11 is a basic  exertion propelled temperature and moisture sensor which is highly used for temperature measuring. It uses a capacitive clamminess sensor and a thermistor to measure the incorporating air, and lets out an electronic sign on the data pin (no straightforward information pins required). Its really simple to use & light weight, yet requires mindful intending to get data in every minutes. Its has three pins. First pin is for vcc, second pin is for GND. Third pin is D0.

Max30100

Max 30100 is also known as an integrated system it is a oximetry device. It can also monitor the heart rate of human body. it is combined with the two LEDs and photodetector, optimised optics and also low noise analog signal processing that can detect pulse oximetry and heart rate of a signal for the human. This device can operate from 1.8v and 3.3v power supplies. Max 30100 can be used in a many applications like wearable device, fitness assistant device and also a medical monitoring devices. The benefit of using Max 30100 is that it can be the both pulse oximeter and heart rate of the human. It has ultra-low-power operation that increase the battery life for the wearable device. High signal into noise ratio provides robust motion artifacts and it has also a fast data output capacity.
