“…Thermocouples can be inaccurate if exposed to moisture, voltage noise, or large variations in ambient temperature, whereas RTDs are expensive and rarely used in cold chain logistics [19,20]. Due to good accuracy and small size [21][22][23][24], many temperature-tracking systems prefer thermistors, but those allowing high accuracy measurements are expensive, fragile and need filters or DC voltage because of their high resistance [25]. In recent years, other techniques have been investigated to measure temperature in cold chain products, e.g.…”
