NTC thermistor sensor for temperature monitoring bracelet

　　Body temperature monitoring usually uses a negative temperature coefficient thermistor (NTC thermistor) as a temperature sensor. The basic principle of the NTC thermistor temperature measurement system is to convert the thermistor value carrying temperature information into the frequency signal of the oscillator, and then sample the frequency signal to obtain the temperature value it represents, that is, at a certain time. The frequency pulse is counted to realize the measurement of temperature change.

　　Committed to the research and development of high reliability and high stability of NTC thermistor sensors and achieved significant results, MF52 series of small head diameter NTC thermistor sensors, its significant advantages are small size, fast response and long-term stable reliable performance. The accuracy can reach up to 0.02℃, which is very suitable for wristband products.

　　long-term stable output

　　High accuracy and wide temperature range

　　Quick response and short response time

　　The diameter of the NTC head is 0.8MM, which can achieve the best effect of rapid response to external temperature

　　After the NTC thermistor is divided into grades, the resistance range of each grade is only 20 ohms, so it can achieve an ultra-high precision of 0.05.

　　Equipped with a chip resistor with the same resistance value as the thermal probe, automatic temperature matching does not require software calibration of each product
