Overview
Description
The HS3101 is a highly accurate, fully calibrated relative humidity and temperature sensor. The MEMS sensor features a proprietary sensor-level protection ensuring high reliability and long-term stability. The hydrophobic membrane covering the lid inlet port prevents particles and liquids from entering the sensor and compromising the performance.
Features
- RH accuracy: ±1.5%RH, typical (10 to 90%RH, 25°C)
- Hydrophobic membrane, IP67 rating
- 14-bit resolution: 0.01%RH, typical
- Fast RH response time: 4 seconds, typical
- Temperature sensor accuracy: ±0.2°C, typical (-10 to +80°C)
- Low current consumption: 1.0µA average (8-bit resolution, 1.8V supply), 24.4µA average (14-bit resolution, 3.3V supply), one RH and temperature measurement per second
- Excellent stability against aging
- Very low power consumption

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.
