I have a Ni passive 2 wires thermo sensor already installed. Is it possible to use it with Arduino Uno? How shall I connect it? Is ther any library I may leverage? Create a voltage divider with a resistor that's roughly the value of this sensor at the average temperature you will use it, then you can read the mid point on an analog pin, calculate the resistance of the PTC, and using the table calculate the temperature I'd just do a linear interpolation between values, will be good enough.

They were not designed to interface directly to a PT RTD, and will not provide good accuracy when measuring these lower resistance sensors. The resistance input type was intended to allow for measuring the position of a 10K potentiometer that is used on some wall sensors. Get Started. Already have an account?

A digital DS18B20 has a resolution of 0. The CSRF token cookie contributes to your security. Is Arduino accurate enaugh to measure Vout variations in the range of mV? Create a voltage divider with a resistor that's roughly the value of this sensor at the average temperature you will use it, then you can read the mid point on an analog pin, calculate the resistance of the PTC, and using the table calculate the temperature I'd just do a linear interpolation between values, will be good enough. Basic price. That is reallly cool. Google Analytics:. I don't know how to use sensor pt Project Guidance. Is ther any library I may leverage?

More information. I have a Ni passive 2 wires thermo sensor already installed. The CSRF token cookie contributes to your security. Then I will use Steinhart-Hart proxy to get accurate interpolation. To calculate the resistance of the PTC you don't need to know the input voltage, as all you need to know is the ratio between the two resistors, and that's what the ADC reading really gives you. The waterproof version already has a cable attached. The cookie is used to store the site user's cookie settings over multiple browser sessions. I alredy used them and are they really good and cheap. Get a different probe. Wow, I have a lot to learn yet! Google Analytics:. It's got a table of resistor values, showing this is a PTC. Project Guidance. Can I use Ni thermo sensor with Arduino Uno?
