Product Specification

HS1101/HS1101LF Capacitive Humidity Sensor

HS1101LF Capacitive Humidity Sensor DESCRIPTION
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.

HS1101LF Capacitive Humidity Sensor FEATURES
? 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
? Individual marking for compliance to stringent traceability requirements
? Part may be washed with distilled water.

HS1101LF Capacitive Humidity Sensor APPLICATIONS
? Automotive
? Home Appliance
