RELATIVE HUMIDITY SENSOR
HS1101LF
Meets RoHS regulations
Based on a unique capacitive cell, these relative humidity sensors are designed for high
volume, cost sensitive applications such as office automation, automotive cabin air
control, home appliances, and industrial process control systems. They are also useful
in all applications where humidity compensation is needed.
MAIN FEATURES
● Lead free components
● Full interchangeability with no calibration required in standard conditions
● Instantaneous desaturation after long periods in saturation phase
● Compatible with automatized assembly processes, including Pb free
wave soldering and reflow processes (1)
● High reliability and long term stability
● Patented solid polymer structure
● Suitable for linear voltage or frequency output circuitry
● Fast response time and very low temperature coefficient
● Part may be washed with distilled water.
● Individual marking for compliance to stringent traceability requirements
