ITEM NAME:Detection hygrometer water sensor module of soil moisture Arduino + sample K3E9 Detection hygrometer water sensor module of soil moisture Arduino + sample K3E9 This is a summary of the soil moisture sensor. It can be used to detect moisture. If the soil is dry, High-output module, Otherwise Low. Garden plants can be managed without the people, This sensor has the automatic cleaning system . Sensitivity adjustment is possible(Street setting is indicated by the photograph of the blue digital potentiometer) Dual output mode, More accurate analog output. Fixing screw holes for easy installation. With Power lamp (red) and digital switching output (green). Stable in the LM393 comparator chip. Color: As shown The dimensions of the panel substrateï ¼Å¡3 cm × 1.5 cm The dimensions of the soil sample: 6 cm × 2 cm The total length: 21 cm Interface Description (4-wire)ï ¼Å¡VCCï ¼Å¡3.3Vï ¼Å¸5V DOï ¼Å¡Digital output interface (0 and 1) AOï ¼Å¡Analog output interface procedure: In order to detect the moisture content of the soil, In general, will be used when the most sensitive to the ambient humidity. To reach the module, Adjust the threshold in soil moisture, Set threshold, When the module is increased to low soil moisture D0 output, The port output is high. Digital output D0 in order to directly detect the soil moisture, It can be connected to the minicontroller The digital outputs it is possible to form the shop relay DO module soil moisture equipment, can be used to directly drive the summer module. Analog output AO and AD modules are connected through the AD converter, You can see the detailed values of the soil moisture.If the soil is dry, High-output module, Otherwise Low. DOï ¼Å¡Digital output interface (0 and 1). AOï ¼Å¡Analog output interface.
