When an electronic item is moved from a cold place (e.g., garage, car, shed, air conditioned space in the tropics) to a warm humid place (house, outside tropics), condensation may coat circuit boards and other insulators, leading to short circuit inside the equipment.
A humidistat or hygrostat is an electronic device analogous to a thermostat but which responds to relative humidity, not temperature. A typical humidistat is usually included with portable humidifiers or dehumidifiers. It can also be included with combined air cleaner or humidifier units to control a home's humidity level or any other indoor ...
Electronic dry boxes contain a small Peltier cooler, which removes moisture from the air by condensing it out. A control dial is usually provided that permits the user rough adjustment of the humidity level. More sophisticated designs link the cooler to a settable digital hygrometer, allowing very precise humidity level control.
Silica gel is widely used to buffer relative humidity inside museum display cases, packaged clothing, electronics and anything that might be damaged by condensation, or in the example of museum display cases, being too low an RH (relative humidity) as the silica will help protect the objects displayed from mechanical damage due to shrinking and ...
Example of a temperature/humidity chamber Example of a Walk-In Environmental Chamber used for automobile reliability testing in various simulated environment. An environmental chamber, also called a climatic chamber or climate chamber, is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and ...
It relates to the packaging and handling precautions for some semiconductors. The MSL is an electronic standard for the time period in which a moisture sensitive device can be exposed to ambient room conditions (30 °C/85%RH at Level 1; 30 °C/60%RH at all other levels). Increasingly, semiconductors have been manufactured in smaller sizes.
Here are some vintage electronics that might make you a few bucks if you happen to have them hidden away somewhere. Also see how much your 1980s toys could be worth. Original Apple iPod
Computer equipment generates heat, and is sensitive to heat, humidity, and dust, but also the need for very high resilience and failover requirements. Maintaining a stable temperature and humidity within tight tolerances is critical to IT system reliability.
