1TECHNICAL DATA
RELATIVE HUMIDITY MODULE
HM 1500
Based on the rugged HS1101 capacitive humidity sensor, HM1500 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
G Small size
G Not affected by water immersion
G Full interchangeability
G High reliability and long term stability
G Typical 1 to 4 Volt DC output for 0 to 100 % RH at 5 V DC supply
G Calibrated within +/- 2 % RH @ 55 % RH
G Very low temperature dependence
G Ratiometric to voltage supply within the specified range
G Suitable for 3 to 7 Volts supply voltage
HM 1500
HUMIDITY SENSOR SPECIFIC FEATURES
G Instantaneous de-saturation after long periods in saturation phase.
G Patented solid polymer structure.
G High resistance to chemicals.
G Fast response time.
