Abstract
• —My project presents the design method for a low cost asynchronous web-server
based on ESP32 interfaced with
• DHT 11 sensor for monitoring temperature and humidity in real-time.
• Environmental management is a key research area where many strategies are being
put by researchers in order to control and manage temperature and humidity in order
to keep processes running there is need to develop a low cost and power consuming.
• Web server to monitor real time conditions of temperature and humidity in various
settings.
• IndexTerms ,ESP32,Web server,DTH 11

DOMAIN :
•EMBEDDED SYSTEMS
An embedded system is a combination of computer hardware
and software designed for a specific function. The systems can
be programmable or have a fixed functionality.
An embedded system is a combination of three major
components. That is Hardware, Application software and Real
time operating system.

•IoT – Internet ofThings
The term IoT or Internet of Things refers to the collective network
of connected devices and the technology that facilitates
communication between device and the cloud, as well as between
the devices themselves.
Examples of IoT products are Smart watches, Smart fire alarms,
Smart security system etc.

INTERNSHIP WORK:
• With getting the hands on experience by working with several sensors such as
temperature and building an app and so on in addition with its embedded coding .
• Building basic projects which includes all the functionalities of the embedded
components which includes the microcontrollers and its code.

Project :Temperature and humidity
detection using ESP32 and Arduino IDE
 DHT11 is a Humidity and Temperature Sensor, which generates calibrated digital output. DHT11 can be
interface with any microcontroller likeArduino, Raspberry Pi, etc. and get instantaneous results.
 DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term
stability. In this project, we will build a small circuit to interface Arduino with DHT11 Temperature and
Humidity Sensor.
 One of the main applications of connecting DTH11 sensor with Arduino is weather monitoring and human
temperature detection

Results :

CONCLUSION :
 The word ‘humidity and temperature change” has begun to draw more attention of
many scientists and researchers. Basically, it refers to a continuous process that has an
alerting and perhaps dangerous consequences.
 .Consequently, these updated techniques reduce the overall system cost; provide real
time observation, low power consumption, lively tracking, real time data processing
and analysis.
 At the end of the day, having such improved national humidity and temperature
monitoring system will positively affect people’s livelihoods
