The HS3104 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: ±3.5%RH, typical (20 to 80%RH, 25°C)
  • Hydrophobic membrane, IP67 rating
  • 14-bit resolution: 0.01%RH, typical 
  • Fast RH response time: 4 seconds, typical
  • Temperature sensor accuracy: ±0.3°C, typical (0 to +70°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
