1. Choose a temperature sensor: Commonly used temperature sensors include the DS18B20 (1-wire), DHT11/DHT22 (digital), and LM35 (analog).
2. Connect the sensor to the ESP32-C3: Make specific pin connections from the ESP32-C3 to the temperature sensor.
3. Write and upload the code: Use a suitable programming environment (like Arduino IDE or PlatformIO) and library to read data from the sensor and perform necessary actions based on temperature readings.

• DS18B20 VCC to ESP32-C3 3.3V
• DS18B20 GND to ESP32-C3 GND
• DS18B20 DQ to ESP32-C3 GPIO (e.g., GPIO4)
• 4.7kΩ pull-up resistor between DQ and VCC

• Connect DS18B20:VCC to ESP32-C3:3.3V
• Connect DS18B20:GND to ESP32-C3:GND
• Connect DS18B20:DQ to ESP32-C3:GPIO4
• Connect a 4.7kΩ resistor between DS18B20:DQ and DS18B20:VCC

1. Install the OneWire and DallasTemperature libraries.
2. Use the following code to read temperature from the DS18B20 sensor:

Cpp
#include 
#include 

// Data wire is plugged into GPIO4 on the ESP32-C3
#define ONE_WIRE_BUS 4

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

void setup() {
  Serial.begin(115200);
  sensors.begin();
}

void loop() {
  sensors.requestTemperatures();
  float temperatureC = sensors.getTempCByIndex(0);
  Serial.print("Temperature: ");
  Serial.print(temperatureC);
  Serial.println("°C");

  delay(1000);  // Wait 1 second before reading again
}

• You need a digital temperature sensor (DS18B20). If you use a different sensor, the wiring and code will differ.
• You use the Arduino IDE. Other environments like PlatformIO or ESP-IDF can also be used.
• The sensor's data wire is connected to GPIO4. You can change it to any other GPIO.
