HDC1080

My quest for the best temperature and humidity sensor ended with the HDC1080 model. Especially in highly humid environments, I tried many sensors on the market and was not satisfied with any of them. Under high humidity, sensor values can deviate significantly. Sometimes differences can reach values like 10-15. If you are looking for a humidity and temperature sensor that works accurately, HDC1080 is perfect for you.

The HDC1080 module is a low-power, high-accuracy module that communicates via the I2C protocol.

TECHNICAL SPECIFICATIONS:

• Relative Humidity Accuracy ±%2 (typical)
• Temperature Accuracy ±0.2°C (typical)
• Excellent Stability in High Humidity
• 14 Bit Measurement Resolution
• 100 nA Sleep Mode Current
• Supply Voltage 2.7 V to 5.5 V
• I2C Interface

A temperature and humidity sensor that works reliably above 75% humidity at an affordable price. It works very reliably even in high humidity in approximately a textile factory. When compared daily with humidity values measured by a TEST brand hygrometer, there is only a 2% difference.

You don't need to spend thousands of dollars on temperature and humidity sensors. Especially in this PCB model, the HDC1080 sensor is placed away from PCB components that could affect the accuracy of the measurement. Thus, it can make the most accurate measurements. HDC1080 also takes more reliable measurements compared to models on the purple PCB that operate with 3.3 volts.

ClosedCube_HDC1080 hdc1080;

void setup() {
    Serial.begin(9600);
    Serial.println("Fixaj.com HDC1080 Arduino Test");
    hdc1080.begin(0x40);
}

void loop() {
    Serial.print("Temperature=");
    Serial.print(hdc1080.readTemperature());
    Serial.print("°C, Humidity=");
    Serial.print(hdc1080.readHumidity());
    Serial.println("%");
    delay(3000);
}
