RELATIVE HUMIDITY MODULE HM1500LF
Compliant with RoHS recommenda tions
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.
MAIN FEATURES
Small size.
Product free from Lead, Cr(6+), Cd and Hg.
Not affected by water immersion.
Full interchangeability.
High reliability and long term stability.
Typical 1 to 3.6 Volts DC output for 0 to 100 % RH at 5 V DC supply.
Calibrated within +/- 2 % RH @ 55 % RH.
Very low temperature dependence.
Ratiometric to voltage sup ply from 4.75Vdc to 5Vdc.
Able to operate from 3 to 10 Volts supply voltage
HUMIDITY SENSOR SPECIFIC FEATURES
Instantaneous de-saturation after long periods in saturation phase.
Fast response time.
Not affected by water immersion.
Part could be washed with distilled water.
Patented solid polym er structure.
