Overview
Description
The HS3003 is a highly accurate, fully calibrated relative humidity and temperature sensor. The high accuracy, fast measurement response time, and long-term stability, along with the small package size, make the HS3003 ideal for a wide number of applications from portable to harsh environments.
An integrated calibration and temperature compensation logic provides fully corrected RH and T values via a standard I²C output. The measured data is internally corrected and compensated for accurate operation over a wide range of temperature and humidity levels–user calibration is not required.
Features
- RH accuracy: ±2.8% RH typical
- Fast RH response time (typical 6 seconds)
- Temperature sensor accuracy: ±0.2 °C typical (-10 °C to +80 °C)
- 14-bit resolution: 0.01% RH (typical)
- Low power consumption: 1.0µA average (one RH+T measurement per second, 8-bit resolution, 1.8V supply)
- Extended supply voltage: 2.3V to 5.5V

How to differentiate versions of HS300X?
Hi all, I've acquired different versions of the HS300X temperature/humidity sensors. Is there any way to differentiate it? The mark on package seems not help, since it has the format H3YW, with Y=year and W= work week code. The sensors have an ID number, but I ...

HS3xxx - False measurement results
After sending a measurement command the sensor enters the measurement state. To elminate false readings, set the delay after sending the measurement command to the minimum time needed specified in the datasheet. This corresponds to at least 35ms for a 14bit RH measurement. During the measurement time it will not ...

HSxxxx - Sensor accuracy problems after assembly
Some assembly processes like SMD reflow soldering can influence the humidity sensing polymer, which results in a temporary measurement offset. To speed up the recovery process, try to recondition the sensor using the recondition routine explained in the datasheet. This will ensure the humidity sensing module to be properly hydrated.
