Tutorial: How to use Temperature and Humidity Sensor AHT10

The AHT10 sensor is a small but powerful device for measuring ambient temperature and humidity. Ideal for environmental monitoring projects, smart home systems, and control systems.

What you need

• Arduino Uno or compatible
• USB cable
• Network connection (optional for data transmission)

Steps

1. Connect the AHT10 sensor pins to an Arduino Uno: VCC to 3.3V, GND to ground, SCL to A5, SDA to A4.
2. Install the Adafruit_AHTX0 library through Arduino’s library manager.
3. Write and upload the example sketch provided by the library.
4. Open the Arduino serial monitor and view the temperature and humidity data.
5. Optimize the received data for display on a monitoring platform or an LCD display.
6. Add a WiFi or Ethernet module to send data to a cloud platform.
7. Check the datasheet to add additional features such as converting data to Fahrenheit or relative humidity percentage.
8. Test the sensor in various environmental conditions to verify its accuracy.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  float temperature = aht.getTemperature();
  float humidity = aht.getHumidity();
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.print(" C, Humidity: ");
  Serial.print(humidity);
  Serial.println(" %");
  delay(1000);
}
