Organic compost fermentation online measurement and control device and method

The invention discloses an on-line measurement and control device and method for organic compost fermentation, the device comprises a fermentation box, a limiting seat a is installed at the rear of the inner side of the fermentation box, the interior of the limiting seat a is slidably connected with a mounting rack, and the outer side of the lower end of the mounting rack is provided with an oxygen content detector, a temperature sensor and a humidity sensor; the servo motor is mounted on the right side of the fermentation box, and the output end of the servo motor is connected with a lead screw. According to the organic compost fermentation on-line measurement and control device and method, fermentation environment parameters in the fermentation box are measured on line through the oxygen content detector, the temperature sensor and the humidity sensor, when the oxygen content or the temperature and the humidity are insufficient, control supplementation is conducted on the fermentation environment parameters
