The utility model discloses a safe cabin based on constant temperature and humidity environmental conditioning belongs to safe cabin field. A safe cabin based on constant temperature and humidity environmental conditioning, includes singlechip, first relay, second relay, third relay, refrigerating system, heating, humidification system and safe house room physically, the singlechip passes through the IO mouth and links to each other with first relay, second relay and third relay. It can be realized air temperature and humidity control in an organic whole, and adopt the less singlechip of power to control, the safe house room body adopts the ya keli board as whole material, built -in heating, and the present invention has a protecting function. Humidification device and temperature and humidity sensor, these device module are connected with the IO mouth of singlechip, the singlechip analysis comes from temperature and humidity data that temperature sensor transmitted, how the judgement should stabilize the humiture condition in the room, and then control temperature regulation and humidity control module realize, the single chip microcomputer control energy consumption is low, the energy saving.
