Problems solved by technology
[0002] The DO sensor is a sensing device used to measure the amount of dissolved oxygen in water. During use, the sensor head needs to be inserted into the water body. When the user stands on land and detects, the water body near the edge Affected by the land and the dissolved oxygen in the overall water body will be different, the sensor head needs to be extended farther, because the transmission line is soft, it will cause inconvenience in use, and the use of support rods will also cause inconvenience in operation and reduce efficiency, while Entering the water body by boat will increase the amount of dissolved oxygen in the water body, which is time-consuming and laborious, and the cost of detection will increase. Taking water samples will also cause changes in the amount of dissolved oxygen. However, the existing DO sensor cannot solve the above problems. Therefore, The invention proposes a DO sensor with strong anti-interference stability
