HM1500LF – Relative Humidity Module • Small size product • Product free from Lead, Cr(6+), Cd and Hg • Humidity calibrated within +/-2% @55%RH • Typical 1 to 3.6 Volt DC output for 0 to 100% RH at 5Vdc supply • Ratiometric to voltage supply from 4.75Vdc to 5Vdc • Patented solid polymer structure DESCRIPTION Based on the rugged HS1101LF capacitive humidity sensor, HM1500LF is a dedicated humidity transducer designed for OEM applications where a reliable and accurate measurement is needed. Direct interface with a micro-controller is made possible with the module’s linear voltage output. FEATURES APPLICATIONS • Full interchangeability • High reliability and long term stability • •• Not affected by water immersion • Suitable for 3 to 10 Vdc supply voltage • •• •• Industrial Process control … Very low temperature dependence Humidity Sensor Specific features Instantaneous de-saturation after long periods in saturation phase Fast response time Part could be washed with distilled water (1) Soldering temperature profiles available on request / contact us at humidity.application@meas-spec.com PERFORMANCE SPECS MAXIMUM RATINGS Ratings Storage Temperature Storage Humidity Supply Voltage (Peak) Humidity Operating Range Temperature Operating Range HM1500LF HPC062_F Symbol Tstg RHstg Value -30 to 70 0 to 100 Unit °C % RH Vs RH Ta 10 0 to 100 -40 to 60 Vdc % RH °C www.meas-spec.com 1/5 October 2012 HM1500LF – Relative Humidity Module ELECTRICAL CHARACTERISTICS (Ta=23°C, Vs=5Vdc +/-5%, R L>1MΩ unless otherwise stated) Humidity Characteristics Humidity Measuring Range Relative Humidity Accuracy (10 to 95% RH) Supply Voltage (regulated at 5Vdc*) Nominal Output @55%RH (at 5Vdc) Current consumption Temperature Coefficient (10 to 50°C) Average Sensitivity from 33% to 75%RH Sink Current Capability (RL=33kΩ) Humidity Hysteresis Time Constant (at 63% of signal, static) 33% to 75%RH Warm up time (electronic) Humidity resolution Output Impedance Symbol RH RH Vs Vout Ic Tcc ∆Vout/∆RH Is Min 0 2.42 Typ +/-3 5 2.48 1.4 - 0.05 +26 Max 100 +/-5 2.54 2 -0 .1 150 +/-1 10 τ tw 150 0.4 70 Z Unit %RH %RH Vdc V mA %RH/°C mV/%RH µA %RH s ms %RH Ω *Maximum power supply ramp up time to Vcc should be less than 4ms. TYPICAL PERFORMANCE CURVES HUMIDITY SENSOR • Measurement conditions HM1500LF is specified for accurate measurements within 10 to 95% RH. Excursion out of this range (95% RH, including condensation) does not affect the reliability of HM1500LF characteristics. Dedicated HM15XX products are available for extreme RH conditions (as HM1520 for low dewpoints).
