Online monitoring system for harmful gas in poultry house and monitoring method thereof

The invention discloses an online monitoring system for harmful gas in a poultry house. The online monitoring system comprises a sampling shell. The sampling shell is divided into three chambers by partition plates, and the partition plates are arranged with through holes. A first ammonia gas sensor and a second ammonia gas sensor, a first hydrogen sulfide sensor and a second hydrogen sulfide sensor, and a first carbon dioxide sensor and a second carbon dioxide sensor are respectively mounted in the three chambers, and the first ammonia gas sensor and the second ammonia gas sensor, the first hydrogen sulfide sensor and the second hydrogen sulfide sensor and the first carbon dioxide sensor and the second carbon dioxide sensor are respectively in communication with the controller. Accordingto the online monitoring system for harmful gas in poultry house and monitoring method thereof, the shortcomings of the prior art can be improved, and the accuracy of harmful gas monitoring in a poultry house is improved. 本发明
