This INTEGER reports the lowest ambient temperature observed during the sensor's current sampling window, the counterpart to ambientTempMax, useful for confirming a server's thermal environment stays consistently within an expected range rather than swinging widely. An admin auditing data-center airflow stability checks the spread between ambientTempMin and ambientTempMax to gauge how variable conditions have actually been. A value of 22 alongside a max of 24 would indicate a tight, stable thermal range.
