4. Abstract
• My project presents the design method on ESP32 interfaced with
• DHT 11 sensor for monitoring temperature and humidity in real-time
• The aim of this project is to fabricate a functional hardware and software system
to measure temperature and humidity
• This project utilized an esp32 interfaced with a Temperature and Humidity
sensor.
• A code is generated using the computer with the appropriate Arduino program
and sent to the Arduino IDE for running the circuit.

5. COMPANY PROFILE:

which include both software, and hardware.

6. 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.

7. •IoT – Internet of Things
 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.

8. 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.

9. Project : Temperature and humidity
detection using ESP32 and Arduino IDE
 DHT11 is a Humidity and Temperature Sensor, which generates digital output. DHT11 can be interface
with any microcontroller like Arduino, 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

11. Hardware Components :
•Temperature sensor
•Humidity sensor
•ESP32
•Battery

12. DHT11 SENSOR
•Operating Voltage: 3.5V to 5.5V
•Operating current: 0.3mA
(measuring) 60uA (standby)
•Output: Serial data
•Temperature Range: 0°C to
50°C
•Humidity Range: 20% to 90%
•Resolution: Temperature and
Humidity both are 16-bit
•Accuracy: ±1°C and ±1%

13. ESP32
•Consists of 48 pins with multiple functions in that 34
are GPIO pins
•TXD and RXD are usually used for flashing and
debugging
•ROM− 448 KB (for booting and core functions)
•SRAM− 520 KB
•Integrated Connectivity Protocols− WiFi, Bluetooth,
•Operating temperature range− −40 − 85 degrees
Celsius
•Operating Voltage− 3.3V
•Operating Current− 80 mA (average)

14. Software Tool :
• Arduino IDE
• The Arduino Integrated Development Environment - contains a
text editor for writing code, a message area, a text console, a
toolbar with buttons for common functions and a series of
menus. It connects to the Arduino hardware to upload
programs and communicate with them.

15. • Arduino IDE

16. Results :
• After opening the code with Arduino IDE
• Compile and upload code to ESP32 board by clicking upload button on
Arduino IDE
• Make the sensor colder or hotter. for example putting the sensor near a
hot cup of coffee
• Result will be displayed on serial monitor as shown in the above figure

17. 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
