That accuracy spec covers the sensor element and on-chip calibration — no external compensation or lookup table needed in firmware. Response time is 6 seconds typical, which means the reading settles fast enough for environmental monitoring in HVAC or server-room air handling but is not intended for fast-moving air streams or condensation detection. Operating temperature spans -40°C to 125°C, so the sensor survives reflow soldering and can be placed in airflow paths that see hot exhaust or cold outdoor intake without derating. ## Field-swap and integration notes No separate analog supply pin; the sensor draws its power from the same rail as the digital interface. Surface-mount package in strip form — no socket option, so field replacement requires a hot-air station or reflow oven. The 14-bit I²C address is fixed; confirm it does not conflict with other devices on the same bus before the board spins.","metaTitle":"Renesas HS3003 Humidity & Temp Sensor, 14-bit, I²C, ±2.5% RH","metaDescription":"HS3003 from Renesas Electronics: active-production humidity & temperature sensor, 14-bit I²C output, ±2.5% RH accuracy, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"series":"HS300x","has_mpn":"HS3003","output_type":"14b","sensor_type":"Humidity, Temperature","accuracy_pct":"2.5","package_type":"Strip","mounting_type":"Surface Mount","output_signal":"I²C","product_status":"Active","lifecycle_stage":"eol_hot","humidity_max_pct":"0 to 100% RH","response_time_ms":"6.0","supply_voltage_v":"1.8","Operating Temperature High":"-40°C to 125°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.44","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/905aebd547d54748d335f697bc6b9c8b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/HS3003/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/HS3003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/HS3003 when reusing this data.
