Soil Moisture Sensor in Pakistan

This is a simple Soil Moisture Sensor, can be used to detect soil moisture Module Output is high level when the soil moisture deficit,or output is low Can be used in module plant waterer device, and the plants in your garden no need people to manage

Soil moisture sensors measure the volumetric water content in soil.[1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the moisture content.

The relation between the measured property and soil moisture must be calibrated and may vary depending on environmental factors such as soil type, temperature, or electric conductivity. Reflected microwave radiation is affected by the soil moisture and is used for remote sensing in hydrology and agriculture. Portable probe instruments can be used by farmers or gardeners.

Instructions for Use:

Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil
Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low

The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moistureAlso fit for electronic games, electronic building blocks, Arduino designs etc
