Smart fume hood

A smart fume hood, used for extracting an experimental waste gas generated by an experimental liquid and electrically connected to a blockchain network, the smart fume hood comprising:

• a fume hood, comprising:
• an experimental tank, used for holding the experimental liquid;
• a moving door, movably connected to the experimental tank;
• and
• a peristaltic pump, linked to the experimental tank and used for extracting the experimental waste gas;
• a chipset, located in the fume hood, wherein the chipset comprises a blockchain information tracking part, and the blockchain information tracking part is electrically connected to the blockchain network and used for recording a source of the experimental liquid and logistics information of the experimental liquid on the blockchain network for traceability;
• and
• a detection module, located in the fume hood and electrically connected to the chipset, wherein the detection module is used for measuring at least one gas property of the experimental waste gas.
