Overview
Description
The HS4001 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 HS4001 is fully calibrated and temperature compensated with an I2C digital output.
Features
- Humidity range: 0% to 100%RH
- RH accuracy: ±1.5%RH, typical
- I2C digital output
- 14-bit resolution
- Fast RH response time: 4 seconds, typical
- Temperature sensor accuracy: ±0.2°C, typical (-10°C to +80°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
