This repository contains the hardware, firmware, and drivers for MultiTherm.
MultiTherm allows you to log data from a few tiny I2C temperature sensors via your computer's USB port. A few could range from 1-4 or more.
Each temperature sensor is on a flexible 200mm probe ribbon; route them in free space however you like, or even trim their ribbons to length. An adhesive sticker provides thermal coupling to your device under test.
MultiTherm can be used as a lower-cost substitute for a resistance temperature detector (RTD) and data acquisition interface (DAQ) while still featuring NIST-traceable calibration accurate within ±0.1°C (between –20°C to 50°C) and 0.0078°C read-out resolution.
Working temperature range is –55 °C to 150 °C.
MultiTherm will be made available for purchase at a later date.
