Some Parents Asked Whether the Sensor Supports Measuring the Soil Humidity Value. the Technology Popularized the Knowledge. the Humidity Value Is for Air, Which Refers to the Quality of Water Contained in One Cubic Meter of Air, however, Due to the Uneven Dissolution of Water in the Soil, This Index Cannot Be Measured and Has No Discussion Value. This Board Can Generally Measure the Humidity and Decide the Switch of Watering Equipment According to the Humidity Condition, and the Sensitivity Can Be Roughly Adjusted by Potentiometer. Many Sets of Products Are Sold, the Quality Is Stable, Trustworthy!
This Product Does Not Need Programming Or Single Chip Microcomputer, So Please Do Not Force Us to Provide Code.
This Product Does Not Provide Power Supply. You Can Use Power Bank (5V Dc) as the Power Supply, Or Use 4 No. 5 Battery Boxes and Install 4 Batteries to Supply Power.
for Each Part of the Test:
1. Test Relay Module: Connect the Relay Module Vcc to 5V, Gnd to Ground, in to Gnd, the Relay Beats, in to Hang, the Relay Recovers, So the Relay "Card" Can Be Heard Repeatedly;
2. Test the Soil Moisture Sensor Module: Connect the Fork Probe and the Transmitter Module with Two Dupont Wires. the Transmitter Module Vcc Is Connected to 5V, Gnd Is Grounded, Red Power Light Is Always on When the Power Is Just on, Green (Blue) the Color Indicator Light Blinks Once; Insert the Fork Probe Directly into the Water, and the Green (Blue) Color Indicator Light Is on;
3. Connect the Red Line of the Water Pump to 5V, Ground the Black Line, and Work the Water Pump. Pay Attention to the Test for 1 Second, and Do Not Expose It to the Air for a Long Time;
4. Assemble It According to the Schematic Diagram.
Note:
1. This Product Is Free of Welding, but You Need to Peel the Wire, Twist the Copper Wire Together, and Protect It with Black Tape;
2. the Water Pump Cannot Run in the Air for a Long Time;
3. the System Is Connected, Powered on, and the Water Pump Has Been Working All the Time. It Is Right. Because in the Air, the Probe Cannot Reach the Humidity, So the Water Pump Has Been Working All the Time, there Is No Problem If It Is Correctly Installed in the Flowerpot.
