1 TECHNICAL DATA
RELATIVE HUMIDITY SENSOR
HS 1100 / HS 1101
Based on a unique capacitive cell, these relative humidity sensors are designed for high
1
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.

FEATURES
● Full interchangeability with no calibration required in standard conditions
● Instantaneous desaturation after long periods in saturation phase
● Compatible with automatized assembly processes, including wave soldering,
reflow and water immersion (1)
● High reliability and long term stability
● Patented solid polymer structure
● Suitable for linear voltage or frequency output circuitry
● Fast response time
● Individual marking for compliance to stringent traceability requirements
