The Crowtail- Thermistor Temperaturen Sensor uses a Thermistor to detect the ambient temperature. The resistance of a thermistor increases when the ambient temperature decreases, so the Arduino can detects the voltage and thus to caculate the current temp https://elecena.pl/product/6056963/crowtail-thermistor-temperature-sensor-2-0 2016-05-07 https://elecena.pl/product/6056963/crowtail-thermistor-temperature-sensor-2-0 2025-12-17
