High Performance Relative HS300x Humidity and Temperature Sensor Datasheet Description Features The HS300x (HS3001, HS3002, HS3003, and HS3004) series is a Humidity range: 0% to 100%RH highly accurate, fully calibrated relative humidity and temperature Humidity accuracy: 1.5%RH, typical (HS3001, 10 to 90%RH, sensor. The MEMS sensor features a proprietary sensor-level 25C) protection, ensuring high reliability and long-term stability. 14-bit resolution: 0.01%RH, typical Integrated calibration and temperature-compensation logic pro- Independent programmable resolution settings: 8, 10, 12, vides fully corrected RH and temperature values via a standard I2C 14 bits output. No user calibration of the output data is required. Fast RH response time: 1 second time constant, typical (with The high accuracy, fast measurement response time, and long- 1 m/sec air flow), 4 seconds time constant, typical (in still air) term stability combined with the small package size makes the Temperature sensor accuracy: 0.2C, typical (HS3001, HS300x series ideal for a wide number of applications ranging from HS3002, -10 to +80C) portable devices to products designed for harsh environments. Low current consumption: 1.0A average (8-bit resolution, The HS300x series digital sensor accurately measures relative 1.8V supply), 24.4A average (14-bit resolution, 3.3V humidity and temperature levels. The measured data is internally supply), one RH and temperature measurement per second corrected and compensated for accurate operation over a wide Excellent stability against aging range of temperature and humidity levels user calibration is not Highly robust protection from harsh environmental conditions required. and mechanical shock Very low power consumption Typical Applications Climate control systems Physical Characteristics Home appliances Supply voltage: 2.3V to 5.5V Weather stations Extended supply voltage: 1.8V (-20C to +125C) Industrial automation Operating temperature: -40C to +125C Medical equipment 3.0 2.41 0.8 mm DFN-style 6-LGA package Automotive cabin climate control Product Image 2021 Renesas Electronics Corporation 1 R36DS0010EU0701 August 9, 2021 HS300x Datasheet Contents 1.
