Soil Humidity Temperature Sensor + Soil Moisture Content Transmitter
Rapid measurement method: select the appropriate measurement location, to avoid the stones, to ensure that the needle does not hit hard objects such as stones,
According to the required depth measurement planing surface soil, to maintain the original soil below the degree of tightness, grip the sensor vertically into the soil, insert,
Not before and after the rock, to ensure close contact with the soil, a small measure of the proposed measurement points to obtain the average of several measurements.
Buried measurement method:
Vertical digging diameter greater than 20 cm pit depth according to the measurement needs, and then the depth of the probe will be inserted into the pit depth of the hole, the pit fill compaction to ensure that
And soil in close contact with the stability of a period of time, can be continuous for several days, months or even longer measurement and recording.
If you are teaching hard surface measurements, you should drill holes (the diameter should be less than the diameter of the probe)
And then inserted into the soil and soil compaction and measurement, the sensor should be to prevent severe shock and shock,
More can not use a hard object percussion. As the sensor is a black package, in the light of the second sensor rapid warming, (up to 50C or more)
In order to prevent excessive temperature on the sensor temperature measurement have an impact, please pay attention to shade in the field or field use and protection.
