Treatment Treatment of birthmarks Salmon patches, Mongolian blue spots and many moles never need treatment. They are either harmless or shrink and fade over time. However, port wine stains, strawberry marks and some moles may need treatment. This is usually if the birthmark causes problems or if it significantly affects your childâs appearance. The main treatments are listed below. Strawberry marks Most strawberry marks donât need treatment.
A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.The word is a portmanteau of thermal and resistor.Thermistors are widely used as inrush current limiter, temperature sensors (NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements. thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.
NTC (negative temperature coefficient) thermistors change their effective resistance over temperature. The most common equation used to model this change is the Steinhart-Hart equation.It uses three coefficients to characterize the NTC material with great accuracy. Use the thermistor and a reference resistor to make a voltage divider. 2  Take the middle of the voltage divider and feed it into an analog-to-digital converter. 3  Measure the ADC voltage in software. 4  Using your knowledge of the reference resistance, and the thermistor's R vs. T curve, convert from ADC counts to temperature.
