HM1500LF Temperature and Humidity Sensor 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.

HM1500LF Temperature and Humidity Sensor FEATURES 
• Small size product
• Product free from Lead, Cr(6+), Cd and Hg
• Humidity calibrated within +/-2% @55%RH
• Typical 1 to 3.6 Volts DC output for 0 to 100 % RH at 5 V DC supply
• Ratiometric to voltage supply from 4.75Vdc to 5Vdc.
• Patented solid polymer structure 
• Full interchangeability
• High reliability and long term stability
• Not affected by water immersion
• Very low temperature dependence
• Suitable for 3 to 10 Vdc supply voltage
Humidity Sensor Specfic Features
• Instantaneous de-saturation after long periods in saturation phase.
• Fast response time.
• Part could be washed with distilled water.
