It outputs 16-bit digital data over an I²C bus, with a typical accuracy of 1.5% RH — this is the headline spec that determines fit for environmental monitoring loops. ## 4 ms response time — fast enough for condensation detection The 4 ms response time covers a step change in humidity — fast enough for closed-loop HVAC damper control or condensation detection on a cold surface. For applications that poll at 10 Hz or slower, the sensor's settling time is negligible. The I²C interface runs at standard and fast-mode rates; no dedicated clock line beyond the bus master's SCL is needed. The 16-bit output gives 0.005% RH resolution per LSB at the typical accuracy level.","metaTitle":"TI HDC3022DEJR Humidity Sensor, 1.5% RH, I²C, 16b","metaDescription":"Texas Instruments HDC3022DEJR humidity and temperature sensor, 1.5% RH accuracy, I²C output, 16-bit resolution, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"output_type":"16b","sensor_type":"Humidity, Temperature","accuracy_pct":"1.5","package_type":"Tape & Reel (TR) Cut Tape (CT)","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":"$2.62","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/85ff32e5253fd556a4d3ec2e0912409d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/HDC3022DEJR/alternatives.json"},"ai":{"faq":[{"question":"How can I get pricing and availability for the HDC3022DEJR?","answer":"The HDC3022DEJR is sourced to order against an RFQ through independent and authorized distribution."},{"question":"What is the output type and interface of the HDC3022DEJR?","answer":"The HDC3022DEJR outputs 16-bit digital data over an I²C bus.
