Note: "Beta" Value 3950

This is a pack of 5 small 10k nominal NTC thermistors, through hole mount (or connect wires, or whatever...)

An NTC reduces in resistance as the temperature rises, and vice-versa, with 10k resistance (within 1%) corresponding to 25 degrees C.

Small thermistors like these are often used to sense the temperature of heatsinks, batteries, ambient temperature etc...

Reading this (or any NTC/PTC) sensor with your micro controller (eg Arduino) is very simple, I've included some basic Arduino code and wiring below. For more details about using NTC, lookup table creation, non-float approximations, and more than you ever wanted to know, see my NTC Spreadsheet: http://goo.gl/WA2ZOH

Here's that most generic Arduino Code for this thermistor...

// Example Usage: // float degreesC = convertAnalogToTemperature(analogRead(analogPin)); // // Thermistor Wiring: // Vcc -> [10K Resistor] -> [Analog Pin] -> [Thermistor] -> Gnd //

float convertAnalogToTemperature(unsigned int analogReadValue) {. if(analogReadValue == 1023) return 1000.0; return (1/((log(((10000.0 * analogReadValue) / (1023.0 - analogReadValue))/10000.0)/3950.0) + (1 / (273.15 + 25.000)))) - 273.15; }
