The Yocto-MaxiThermistor is a 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-MaxiThermistor is an isolated device: there is an electric isolation between the sensor part and the USB part.
The Yocto-MaxiThermistor is shipped with six tiny NTC thermistors connected to a 10 centimeter wire. You can extend them with any regular electric wire.
The six channel terminal block allows the use of 30-18 AWG wire. If you need to use bigger wire, choose the Yocto-Thermistor-C.
The Yocto-MaxiThermistor 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.
