RELATIVE HUMIDITY AND TEMPERATURE MODULE
HTM1505
Based on the rugged HS1101 humidity sensor , HTM1505 is a dedicated humidity and temperature
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 humidity linear voltage
and direct NTC outputs.HTM1505 is designed for an optimized board to board connection.
MAIN FEATURES
q Suitable for direct board assembly
q Not affected by repeated condensations
q Full interchangeability
q High reliability and long term stability
q Typical 1 to 4 Volt DC output for 0 to 100% RH at 5 V DC supply
q Humidity calibrated within +/- 2% RH @ 55% RH
q Temperature measurement through NTC 10 kohm +/- 3% direct output
q Ratiometric to voltage supply within the specified range
HUMIDITYSENSOR SPECIFIC FEATURES
q Instantaneous de-saturation after long periods in saturation phase.
q Patented solid polymer structure.
q High resistance to chemicals.
q Fast response time.
