2-Pin Thermistor Adapter

A clean analog front-end for any 2-wire NTC thermistor. Screw your thermistor into the onboard terminal block, and the module handles the rest using a 10K reference resistor, voltage divider, and power filtering. Reads out as an ADC voltage proportional to temperature, ready for Steinhart-Hart or simple lookup conversion in firmware. Ideal for enclosure monitoring, fluid temperature sensing, or any project where you need a simple, noise-free temperature reading. Use it standalone with any microcontroller, or snap it into the Genesis Modular system from Axiometa for plug-and-play integration. Works with Arduino IDE, MicroPython, or MicroBlocks.
