ESP32 Technical Specifications
This microcontroller has the following technical specifications.10 Best ESP32 Projects
One fantastic feature of the ESP32 is its versatility because you can use it in the following projects.Attendance System Using Face Recognition on ESP32-CAM Board
In addition to the ESP32-CAM, you need an FTDI programmer, jumper wires, and the Arduino IDE. But before uploading code to the board, connect IO0 to GND to enable flashing mode. Next, make the following connections. After that, open the IDE and go to File > Preferences. Paste this JSON-formatted version of configuration values to the Additional Board Manager URLs. Next, install the ESP32 by Espressif Systems under Tools > Board > Boards Manager. Since there is already an example code in the library, go to File > Examples > ESP32 > Camera, and click CameraWebServer. But before uploading the code, enter your Wi-Fi SSID & password and define the ESP camera module. Do this by uncommenting CAMERA_MODEL_AI_THINKER and commenting on the rest of the modules.Program ESP32 Using Arduino IDE to Blink An LED
You will need the ESP32 module, Arduino IDE, and a USB cable for this project. Connect the ESP32 to your computer via the micro USB port (the red light should turn on). After this, open the Arduino IDE and go to Tools > Boards, then select the ESP32 development board. Next, open the device manager and check which com port the board uses to connect to the computer. After that, navigate to Tools > Port, then select the port that corresponds to the one in the device manager. Once connected, type the following code and upload it to the board. int LED_BUILTIN = 2; void setup() { pinMode (LED_BUILTIN, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, HIGH); delay(1000); digitalWrite(LED_BUILTIN, LOW); delay(1000); } The red LEDs should blink in intervals of one second.Automatic Hand Sanitizer Dispenser with COVID19 Live Updates
The complete ESP32 setup for this project includes the following components.- ESP32 module
- 16x2 LCD
- Ultrasonic sensor
- Mini DC submersible pump
- Relay module
- Hand sanitizer
- Arduino IDE
ESP32 Active Mode and Deep Sleep Mode Power Consumption Comparison
The goal is to use a push button to switch the ESP32 to deep sleep mode. This mode turns off the CPU, Wi-Fi, and Bluetooth, then puts the ULP-Co processor in an on/off state to reduce power consumption. You require the following components.- An LED
- A Push-button
- Two 4.7K resistors
- One 680 ohm resistor
- A breadboard
- A hookup wire
- Power supply unit (5V adapter)
- USB cable
- IDE (Arduino)
ESP32 DHT11/DHT22 Web Server – Temperature and Humidity using Arduino IDE
The DHT11 combines a temperature sensor and a humidity sensor into one module, making it the ideal candidate for interfacing with the ESP32. But you can also use the DHT22. Connecting the two is straightforward because the sensor only has three pins. After that, use the free web-based IFTTT service (If This Then That) to build chains of conditional statements. These lines of code will send out an email whenever the humidity or temperature levels exceed the predefined limit. Apart from measuring the atmospheric humidity levels, you can use the DHT11 as a soil moisture sensor.ESP32 Based Smart Clock with Weather Forecasting
At the heart of this project is the ESP32-WROOM-32 chip. You will also need the following:- Six 1k resistors
- Four 10k and 4.7k resistors
- One 2k and one 470-ohm resistor
- Four 10uF electrolytic capacitors
- Two 100nF ceramic capacitors
- A 2-pins female header
- Three buttons and one buzzer
ESP32 Based Internet Radio using MAX98357A I2S Amplifier Board
Since the world is phasing out analog radios, designing an internet radio is perfect for the digital world. You can build the radio as a standalone, portable version or software operating on a computer to access the internet. For the standalone, portable version, you need the following components.- ESP32 Devkit
- MAX98357A
- An 8-ohm speaker (0.5 – 1W rating)
- 5V 1A charger
- USB cable
- An active internet connection
Smart Wi-Fi Video Doorbell using ESP32 and Camera
A Smart Wi-Fi video doorbell system is a critical security feature for homes and businesses, making this a vital IoT application. You require the following components to set up the circuit.- ESP32-CAM
- FTDI programming board
- AC (220V) to DC (5V) converter
- Two LEDs
- A push-button
- Buzzer
IoT Based Air Quality Index Monitoring System – Monitor PM2.5, PM10, and CO using ESP32
The complete ESP32 for this IoT application requires the following components.- ESP32 module
- DHT11 sensor
- Nova PM sensor SDS011 (PM2.5 & PM10 measurement)
- MQ-7 sensor (CO measurement)
- 0.96’ SPI OLED display module
- Jumper wires
MPU6050 Gyro Sensor Interfacing with ESP32 Board
The last project involves creating a communication interface between the ESP32 and the MPU 6050 gyro sensor. You need the following components.- ESP32 NodeMCU
- MPU6050 accelerometer and gyroscope module
- Jumper wires
