Quad PT100 RTD Temperature Sensor Shield

Four channel RTD temperature sensor shield, compatible with the Arduino Uno form factor. Included LDO and a high-speed level shifter allow connections to any 3.3 or 5V microcontroller (all Arduinos, Raspberry PI, etc) without sacrificing device performance.

Supports 2, 3, and 4-wire measurment modes. Spring terminal connections ensure secure connections in high vibration enviroments. Precision 15-bit ADC allows 0.05 °C temperature resolution for PT100 and PT1000 platnum RTDs. For non-standard applications including thermistors, custom hardware configurations can be accommodated. Contact Technical Support for more information.

Compatible with R3aktor Core devices and our free R3aktor Control Center PC software. Simply connect to a supported R3aktor and start recording data - no software development required. Want to build your own solution - we're happy to help there too. The SEN-30202 RTD shield is based on the MAX31865 IC from Analog Devices and is compatible with existing libraries for Arduino and Raspberry PI.
