Overview
Description
The HS4003 is a highly accurate, ultra-low power, fully calibrated relative humidity and temperature sensor. The MEMS sensor features a proprietary sensor-level protection ensuring high reliability and long-term stability. The HS4003 is fully calibrated and temperature compensated with an I2C digital output.
Features
- Humidity range: 0% to 100%RH
- RH accuracy: ±2.5%RH, typical
- I2C digital output
- 14-bit resolution
- Fast RH response time: 4 seconds, typical
- Temperature sensor accuracy: ±0.25°C, typical (0 to +70°C)
- Low current consumption: 0.3µA average (8-bit resolution, 3.3V supply), 0.62µA average (14-bit resolution, 3.3V supply), one RH and temperature measurement per second
- Excellent stability against aging

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.
