[Jxct]Soil Moisture Measurement Sensor Temperature and Humidity Detector with 3 Pin

1.Soil Moisture Meter Instructions
 

1.1 Quick test method

Select a suitable measurement location, avoid stones, and ensure that the steel needle does not touch hard objects. Discard the topsoil according to the required measurement depth, and maintain the original tightness of the soil below. Hold the soil meter vertically and insert it into the soil. It is not allowed to shake left and right, it is recommended to measure multiple times to find the average value within a small range of one measurement point.

1.2 Buried survey

Vertically dig a pit with a diameter of> 20cm, insert the soil meter steel needle horizontally into the pit wall at a predetermined depth, bury the pit tightly, and stabilize it for a period of time, then you can perform continuous measurement for several days, months, or even longer.

1.3 Precautions

1). All steel needles must be inserted into the soil during measurement.

2). Avoid direct sunlight on the soil meter, which will cause excessive temperature. Pay attention to lightning protection in the field.

3). Do not bend the steel needle violently, do not pull the soil meter lead wire with force, and do not beat or violently hit the sensor.

4). The protection grade of the soil meter is IP68, which can soak the soil sensor in water.

5). Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long time.
