Versatile and Replaceable Digital humidity sensor, a cost-effective component. In the SHT family the capacitive humidity sensors are fully calibrated and provides a digital output ready for interface.
This sensor is based on a unique capacitive cell, this affordable sensor is used in applications such as office automation, HVAC and home appliances and process control too.
HS1101LF Humidity Sensor - Measurement Specialties
This sensor sports a fast response time and very low temperature coefficient. It also has High reliability and long term stability of Parameters.
Humidity Measuring Range 1% - 99% RH. Nominal capacitance at 55% RH is 180 pF.
A Humidity to Frequency Convertor to make a Easy Digital Counter or Embedded Interface using the venerable 555 is shown below.
Correction - R4=49.9kΩ / RV1=50 kΩ potentiometer.
