: Humidity sensor : HS-30P : -20~70 °C : 20~90 %RH (Without condensation) : 20~90 %RH (Do not let it have dewdrops) : -20~60 °C : AC 1 V (50Hz~1KHz) : 0.3 mW : 55 kΩ ( 25°C, 50%RH) : Min 32.3kΩ / Max 99.7 kΩ : shown in Figure 1 : shown in Figure 2 : shown in Figure 3

• Reliability (Impedance value change as relative humidity at 25°C, 50%RH) - Dry heat storage - Cold storage - Damp heat storage - Heat cycle test - Low humidity storage

Recommended Handling Practices:

• Use only within specified conditions.
• Do not disassemble or change any parts.
• Do not touch sensor element.
• Do not apply any direct current to the sensor.
• Do not touch the film and the surface of the sensor.
• In use and stock, freezing, dust, mist, oil, alcohol, corrosive gases or any other dirty/anomalous ambient may cause degradation of the sensor’s characteristics.
• Protect the sensor film from flux/fume and high temperature during the soldering.
• Do not put sensor in water.
