Abstract

The invention relates to the technical field of carbon dioxide sensors, in particular to a teaching display device based on a carbon dioxide sensor, which comprises a teaching box, a carbon dioxide generation mechanism and a carbon dioxide detection mechanism, and the carbon dioxide detection mechanism is composed of a detection cavity, an air bag, an air inlet pipe, a carbon dioxide sensor, an exhaust pipe, an absorption pipe, a ball valve, a telescopic hose and a respirator. According to the teaching display device based on the carbon dioxide sensor, during teaching, a heating pipe is started through a control switch, heat generated by the heating pipe is conducted into the heating chamber through a heat conducting plate, sodium bicarbonate solids in the heating chamber are decomposed after being heated to generate carbon dioxide gas, and the carbon dioxide gas is introduced into a breather pipe from a gas guide pipe; the ball valve is rotated outside the teaching box, carbon dioxide gas enters the telescopic hose through the ball valve, and a user pulls the respirator outside to feel the concentration of carbon dioxide, so that the principle of the carbon dioxide sensor is known.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide sensors, in particular to a teaching display device based on carbon dioxide sensors. Background technique [0002] A carbon dioxide sensor is a machine used to detect the concentration of carbon dioxide. Carbon dioxide is one of the raw materials for photosynthesis of green plants. 95% of the dry weight of crops comes from photosynthesis. Therefore, the use of carbon dioxide sensors to control the concentration has become an important factor affecting crop yield. [0003] Carbon dioxide sensors are widely used in many fields such as industry, agriculture, national defense, medical and health care, environmental protection, aerospace and other fields. According to the application, carbon dioxide sensors are divided into infrared carbon dioxide sensors, which use the principle of non-dispersive infrared to detect CO2 existing in the air , has good selectivity, no oxygen dependence, and is wi...
