Brief introduction

soilSoil water potential measurementsensorDetermine the degree of soil drought by measuring soil water potential.

1Principle and method of gypsum stick:Similar to gypsum block system，The advantage isThe soil does not dissolve, and the distribution of pores is more uniform, so the measurement results are more accurate. Soil water potential measurement can be used in most agricultural and scenic irrigation environmentssensorReplace the tension meter.The disadvantage is that the response speed is extremely slow, which is not suitable for users who need real-time data for online monitoring. Soak in clean water for at least one hour before use.

2Metal probe method: Use stainless steel probe to test based on soil constant. The advantages are fast response speed, simple installation, and corrosion resistance. The accuracy is slightly worse than the gypsum method. Suitable for the vast majority of users. No processing is required before use.

If the sensor receives the following data correctly.

The above data represents:

Water potentialFFX41=65345=65535-65345+1=190/10=-19.0kpa(Read the value and divide it by ten to calculate)

Note:When the data is less than8000When converted to decimal data÷10When the data is greater than or equal to, the decimal point is shifted one place to the left（≥）8000When, useFFFFSubtract this data and add1After converting to decimal data÷10Move the decimal point one place to the left and then add a negative sign before it.
