HS1101

50,000 

  HS1101 Relative humidity sensor  DataSheetBased 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.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
