🔧 Components Involved DHT11 : A digital sensor that measures temperature and humidity . ESP32 : A powerful microcontroller with built-in Wi-Fi and Bluetooth . Smartphone : Used to view sensor data via a web browser or mobile app. 📡 How It Works Sensor Reads Data : The DHT11 periodically measures the temperature and humidity . It sends this data as a digital signal to the ESP32 via a data pin. ESP32 Processes Data : The ESP32 reads the DHT11 data using a library (e.g., DHT.h in Arduino). It then serves the data over Wi-Fi or Bluetooth . Phone Displays Data : Option 1: ESP32 runs a web server . Your phone connects to the ESP32’s Wi-Fi or local network. Open a browser and go to the ESP32’s IP address to see the data. Option 2: Use Bluetooth to send data to a custom app or Bluetooth terminal. ✅ Simple Use Case (Web Server) ESP32 creates a Wi-Fi hotspot or connects to your router. It runs a web page showing temperatur...

About ESP 32 dev : Dual-core Tensilica Xtensa LX6 processor Built-in Wi-Fi (802.11 b/g/n) Bluetooth 4.2 (Classic + BLE) Multiple GPIO pins  (input/output control) Analog to Digital Converters (ADC)  and Digital to Analog Converters (DAC) PWM, I²C, SPI, UART , and other communication interfaces Flash memory and RAM  (typically 4MB Flash, 520KB SRAM) Low power modes  for battery-powered applications example : TOUCH SENSEING =                  The ESP32 uses capacitive sensing to detect changes in electrical charge. When a finger touches or comes close to a touch-capable GPIO pin , it changes the capacitance at that pin. The ESP32 measures this change and can trigger an action e.g., turning on a light, registering a button press. code : int ledPin = 2 ; void setup () {   // put your setup code here, to run once: Serial . begin ( 115200 ) ; pinMode ( ledPin, OUTPUT ) ; } void loop () {   // put your...
