How does the temperature and humidity alarm sound?

There are generally two ways of sounding temperature and humidity alarms: buzzer sounding and voice prompts. Among them, buzzer sound is a common way. When the temperature or humidity exceeds the set range, the alarm will make a sharp sound through the built-in buzzer to remind the user to pay attention. Some high-end temperature and humidity alarms use voice prompts. When the temperature or humidity is abnormal, the alarm will issue a voice prompt through the built-in voice module to inform the user of the abnormality.
