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.
