Quick Start Guide : NTC Thermistor NXFT15XH103FA2B030 Thermistor Thermistor is resistive component whose resistance value varies in respond to its temperature. NXFT15XH103FA2B030 as standard item for starter kit has 10kohm at 25degC. Copyright © Murata Manufacturing Co., Ltd. All rights reserved.
Hardware & Software Operation On the board, Vcc (3.3V ~ 5V) is applied to thermistor and reference register (6.2kohm) and divided voltage is obtained at OUT. Vcc Ref.(6.2k) Resistor Intaking OUT into ADC port and applying approximation formula, we obtain temperature value.
Pin Connection Pin connection to each CPU board is also instructed in sample code. Evaluation Board Arduino UNO VCC 5V OUT A0 GND GND example : connect to Arduino Copyright © Murata Manufacturing Co., Ltd. All rights reserved.
