HDC3020  
SNAS778 – JUNE 2021  
HDC302x High-Accuracy, Low-Power, Digital Humidity and Temperature Sensor With  
Ultra-Low Drift  
1 Features  
3 Description  
Relative humidity (RH) sensor:  
– Operating range: 0% to 100%  
– Accuracy: ±1.5% typical  
– Drift Correction: reduces offset to return device  
to within accuracy specification  
– Long-term drift: 0.21%RH/yr  
– Condensation protection with integrated heater  
Temperature sensor:  
– Operating range: -40°C to 125°C  
– Accuracy: ±0.1°C typical  
NIST traceability: Relative humidity & temperature  
Low power: average current 0.7 µA  
I2C interface compatibility up to 1-Mhz speeds  
– Four selectable I2C addresses  
– Command/data protection through CRC  
checksum  
The HDC302x is an integrated capacitive based  
relative humidity (RH) and temperature sensor, which  
provides high accuracy measurements over a wide  
supply range (1.62 V – 5.5 V), along with ultra-low  
power consumption in a compact 2.5-mm × 2.5-mm  
package. Both the temperature and humidity sensors  
are 100% tested and trimmed on a production setup  
that is NIST traceable and verified with equipment that  
is calibrated to ISO/IEC 17025 standards.  
Drift Correction reduces RH sensor offset due to  
aging, exposure to extreme operating conditions, and  
contaminants to return device to within accuracy  
specifications. For battery IoT applications, auto  
measurement mode and ALERT feature enable low  
system power by maximizing MCU sleep time. There  
are four different I2C addresses that support speeds  
up to 1 MHz. A heating element is available to  
dissipate condensation and moisture.  
Supply voltage: 1.62 V to 5.50 V  
Available auto measurement mode  
Programmable interrupts  
Programmable measurement calibration  
Factory-installed polyimide tape assembly cover  
Factory-installed IP67 rated environmental cover  
The HDC3020 comes in an open cavity package  
without a protective cover. Two device variants have  
a cover option to protect the open cavity RH sensor:  
HDC3021 and HDC3022. HDC3021 has removable  
protective tape to allow conformal coatings and  
PCB wash. HDC3022 has a permanent IP67 filter  
membrane cover to protect against dust and water.  
2 Applications  
Washer & dryer  
Refrigerator & freezer  
Industrial transport  
Cold Chain asset tracking & data logger  
IoT environmental sensors  
Air quality and gas detection  
Humidifier/dehumidifier  
Thermostat  
CPAP and ventilator  
Water leak detector  
IP Camera
