The 0.5% RH accuracy and 16-bit output over I²C mean the sensor delivers a calibrated digital word directly to the ECU microcontroller — no external ADC or linearization lookup table needed. The 4 ms response time supports fast cabin-climate feedback loops where the HVAC controller updates every tens of milliseconds. ## Supply voltage and interface compatibility The sensor operates from a 1.62 V supply, which lets it run on the same 1.8 V rail as the rest of the automotive sensor cluster without a separate LDO. The I²C interface is the standard two-wire bus found on every automotive-grade MCU — no special timing controller or level shifter required on the PCB.","metaTitle":"TI HDC3020DEFR Automotive Humidity Sensor, 0.5% RH, I²C","metaDescription":"Texas Instruments HDC3020DEFR digital humidity & temperature sensor, 0.5% RH accuracy, 16-bit, I²C, AEC-Q100, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"grade":"Automotive","output_type":"16b","sensor_type":"Humidity, Temperature","accuracy_pct":"0.5","package_type":"Tape & Reel (TR) Cut Tape (CT)","Qualification":"AEC-Q100","mounting_type":"Surface Mount","output_signal":"I²C","product_status":"Active","lifecycle_stage":"eol_hot","humidity_max_pct":"0 to 100% RH","response_time_ms":"4.0","supply_voltage_v":"1.62","Operating Temperature High":"-40°C to 125°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.33","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/78539388e7731145328abb810cd1d06e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/HDC3020DEFR/alternatives.json"},"ai":{"faq":[{"question":"Is the HDC3020DEFR qualified to AEC-Q100 and what grade?","answer":"Yes, the HDC3020DEFR carries AEC-Q100 qualification (the automotive IC stress-test and PPAP standard)."},{"question":"What output interface and resolution does the HDC3020DEFR provide?","answer":"The sensor outputs 16-bit digital data over an I²C bus.
