How does the environmental monitoring system improve the efficiency of poultry farming? The growth and development of livestock and poultry are not only governed by nutrition, genetics and other factors, but also their growth environment has a great impact on the health of the birds. Especially in a confined shed, light and temperature are greatly affected, which can have a great impact on the growth and reproduction of poultry.

The most common of these toxic gases are hydrogen sulfide, carbon dioxide, and ammonia. The indexes of temperature, humidity, light intensity, and concentration of harmful gases in the poultry house can better reflect the growth environment of poultry. Therefore, environmental indicators such as temperature and humidity, light intensity, and toxic and harmful gas concentration must be monitored in real time and accurately, which provides an important reference for future livestock production management.

Due to the high humidity and toxic noxious gases in winter, temperature and humidity sensing has certain dew resistance in order to work in long term harsh environment. Currently, the main types of carbon dioxide sensors are resistive and non-resistive semiconductor sensors, electrochemical sensors, insulated sensors, and non-dispersive sensors. Currently, the most popular ones are electrochemical and semiconductor sensors. There are three broad classifications of sensors for ammonia monitoring: optical type ammonia sensors, metal oxide sensors, and conductive polymer ammonia sensors.
