Thermistor sensor temperature random walk distribution statistics. a The 10 kΩ thermistor sensor temperature measurement data. Due to the temperature digitization, the measurement resolution is limited such that the upper and lower temperature bounds per every one second are recorded. Inset: resonance frequency shift during the temperature measurement period. b The probability distribution for N = 100, P N=100 (m), where \(\bar{m}\) is located at −10.05 and \(\overline{{(\Delta m)}^{2}}\) is 9.97, which is approximately \(\sqrt{N}\) demonstrating that this measurement follows the random walk distribution. The inset shows that the increased number of samples monotonically shifts \(\bar{m}\) far from the centre
