Introduction
This is a simple soil sensor, that may be used to detect soil moisture Output at a high level. In contrast, the soil moisture deficit, or output is low can be used in a module plant water tools, and the plants for your lawn do not need people to manage. The moisture sensor consists of two probes that are used to detect moisture in the soil and moisture sensor probes are coated with immersion gold that protects Nickel from oxidation. The soil moisture module is most sensitive to the ambient humidity and is generally used to detect the moisture content of the soil module to reach the threshold value is set in the sensor, DO output high, when the soil humidity breaks a set threshold value, the DO output low when the soil humidity is less than to a set threshold value. Analog output and AD module connected through the AD converter, you can get more exact values of soil moisture also fit for electronic games, electronic building blocks, Arduino designs, etc
Features of Soil Moisture Meter
- Dual output mode, analog output more accurate
- A fixed bolt hole for easy installation
- With power indicator (red) and digital switching output indicator (green)
- Having an LM393 comparator chip, stable
