The shield has connections for either four 3-wire RTD temperature sensors or three 4-channel RTD temperature sensors or seven 2-wire RTD temperature sensors. An Arduino software library is available below that will make it super easy for you to get temperature readings.
Works with 4-wire, 3-wire, and 2-wire RTDs. Works with Pt-100 and Pt-1000 RTDs. It can also be used as a precision ohmmeter for the Arduino to measure up to 8600 ohms.
This shield uses the ADS1248 analog-to-digital converter (ADC) from Texas Instruments. It features 24-bit resolution (the Arduino ADC is only 10-bit), a programmable gain amplifier (up to 128x), multiple programmable precision current sources, and a ratiometric RTD drive topology to provide you with laboratory-grade, precision readings even in electrically noisy environments. All of these settings have been pre-configured!
