Abstract
A haircare apparatus has a plurality of capacitive sensors, each capacitive sensor configured to provide a capacitance reading indicative of hair proximal to the haircare apparatus. The haircare apparatus has a moisture estimation module configured to estimate, based on capacitance readings of the plurality of capacitive sensors, a moisture level of the hair proximal to the haircare apparatus.
Claims21
A haircare apparatus comprising:
- a plurality of capacitive sensors, each capacitive sensor configured to provide a capacitance reading indicative of hair proximal to the haircare apparatus,
- a moisture estimation module configured to estimate, based on capacitance readings of the plurality of capacitive sensors, a moisture level of the hair proximal to the haircare apparatus,
- an airflow generator configured to provide an airflow to the hair proximal to the haircare apparatus, and
- a controller configured to control the airflow generator based on the estimated moisture level of the hair proximal to the haircare apparatus,
- wherein the moisture estimation module is configured to estimate the moisture level of hair proximal to the haircare apparatus based on a value indicative of airflow temperature at an air outlet of the haircare apparatus.
An attachment for a haircare apparatus, wherein the attachment comprises a plurality of capacitive sensors, each capacitive sensor configured to provide a capacitance reading indicative of hair proximal to the attachment, and a moisture estimation module configured to estimate, based on capacitance readings of the plurality of capacitive sensors, a moisture level of the hair proximal to the attachment, wherein the moisture estimation module is further configured to estimate the moisture level of hair proximal to the attachment based on a value indicative of airflow temperature at an air outlet of the attachment.
