The electronic level includes a ruler body and a level bubble. The two sides of each end of the level bubble are respectively provided with an infrared emitting tube and an infrared receiving tube which are connected to the power supply and correspond to the positions. connected to the electronic circuit. During measurement, when the bubble moves to the left or right, the light intensity of the infrared receiving tube at the corresponding end changes, so that the output end generates a corresponding low level, and the position of the bubble is displayed after passing through the electronic circuit.
Compared with the traditional level, the electronic level has better accuracy and sensitivity because the infrared receiving tube has a certain receiving range for infrared emission and higher sensitivity to light.
