Description

Technical Field

[0001] The present invention relates to the technical field of ancient tree monitoring, and particularly relates to an intelligent ancient tree microenvironment monitoring sensor device and a calibration method thereof. Background Art

[0002] Due to their long tree ages, ancient trees are prone to physiological function decline. To ensure the normal growth and survival of ancient trees, human intervention is required. Personnel need to intelligently monitor the microenvironment of ancient tree growth in real time. When monitoring the microenvironment, a monitoring sensor device is needed. Personnel install the monitoring sensor device on the ancient tree, and the probe of the monitoring sensor device is inserted into the soil to monitor the nutrients and acidity in the soil, ensuring that the ancient tree can absorb the nutrients in the soil to ensure the normal growth of the ancient tree.

[0003] According to CN202110431047.3, the present invention relates to the technical field of sensors, and discloses an atmospheric temperature and humidity monitoring sensor, including a sensor body. An L-shaped plate is movably connected to the surface of the sensor body. A circular hole is formed in the surface of the L-shaped plate. A first threaded rod is movably connected to the inner wall of the circular hole. A nut is threadedly connected to the surface of the first threaded rod. For this atmospheric temperature and humidity monitoring sensor, by providing a bolt, a round block, a knob, a second threaded rod and a moving block, through the cooperation of the bolt and the round block, rotating the bolt moves the round block to press against the elastic belt to fix the elastic belt. Then, through the cooperation of the knob and the second threaded rod, holding the knob drives the second threaded rod to rotate, so that the moving block fits with the sensor body to restrict and fix the sensor body, thereby making the installation of the temperature and humidity sensor relatively simple, without wasting a lot of time, and thus improving the monitoring efficiency of the temperature and humidity sensor.

[0004] However, the monitoring sensor device is generally composed of a main body and a sensor. The main body generally has a plastic shell and other structures to protect the internal parts. The main body is installed on the ancient tree. Since the wind speed and humidity in the growth area of the ancient tree are relatively high, and the main body is exposed outside for a long time, it is easy to cause the main body to be directly oxidized and eroded by sand and wind, affecting the service life of the main body.
