The Yocto-Thermistor-C is an USB interface for NTC and PTC thermistors. It can measure up to six temperature points. Each of the six channels can be configured independently thanks to tables or reference temperatures and β coefficients. The Yocto-Thermistor-C is an insulated device: there is an electric insulation between the sensor part and the USB part.

The Yocto-Thermistor-C is shipped with six tiny NTC thermistors connected to a 10 centimeter wire. You can extend them with any regular electric wire.

All six channels share one contact allowing the use of a bigger terminal and bigger wire (26-16 AWG). If you wish to connect the thermistors in a independent manner, choose the Yocto-MaxiThermistor.

The Yocto-Thermistor-C can also be used as a multichannel ohm-meter.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.

Is it possible to connect six 2-wire PT100s to the Thermistor-C? And if so, would the accuracy of the temperature measurements be improved compared to the Murata thermistors which come with the device?

@liz: This device is optimized to measure larger resistances, ideally around 10K. At around 100 Ohm, the precision will not be better than ~1%, which will not work well for measuring a Pt100 probe.

For Pt100, I really recommend using the Yocto-PT100, which supports 4-wire configuration and has a much higher precision.

Yoctopuce, get your stuff connected.
