Fast response time humidity sensor HC103M2

relativeSMDthin-film

The HC103M2 is a capacitive humidity sensor with a very short response time, even at very low temperatures. This makes it ideal for accurate measurement in the upper atmosphere with radiosondes and weather balloons. The sensor is manufactured using state-of-the-art thin film technology and is suitable for SMD assembly. Its design and choice of materials result in excellent linearity, high sensitivity, and reproducible temperature dependence, which greatly facilitate integration into systems. HC103M2 is supplied on tape and reel, suitable for standard SMD assembly machines. - Extremely fast response time based on proven thin-film technology - Ideal for weather balloons and demanding meteorological applications - Excellent linearity and high sensitivity - Reproducible temperature dependence - Supplied on tape and reel for SMD assembly Technical Specifications: - Nominal capacitance C0 (at 30°C / 86°F): 160 ± 40 pF - Sensitivity: 0.55 pF / % RH - Working range humidity: 0...100% RH - Working range temperature: -80...60 °C (-112...140 °F) - Linearity error (0...98% RH): < ± 2% RH - Response time t63: < 3 s at 23°C / < 15 s at -20°C
