Yocto-MaxiThermistor USB 6 Thermistor Channel

The Yocto-MaxiThermistor is a USB interface for NTC and PTC thermistors, it converts 6 thermistors into a USB interface.

It can measure up to six temperature sensors. 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.

Yocto-MaxiThermistor is shipped with six tiny NTC thermistors connected to a 10 cm 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.
