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. Another form of electronic dry box technology utilizes multi-porous molecular sieve desiccants to absorb moisture.
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 ...

The central controller has one point-to-point data communication wire connected to each module. The protocol between the central controller and the modules uses a 5V pulse width encoding as follows: A header that is 4100 μs high and 300 μs low; One pulse per I/O port, i.e. 16 pulses for input modules and 8 pulses for output modules
This has usually been a blotting paper impregnated with cobalt(II) chloride base; Less toxic alternatives include other chemicals such as cobalt-free chloride base and special plastic films. [1] Humidity indicators are an inexpensive way to indicate or quantify moisture content inside sealed packaging. They are available in many configurations ...
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC).. IEC 60068 is a collection of methods [1] for environmental testing of electronic equipment and products to assess their ability to perform under environmental conditions including extreme cold and dry heat.
