Assembly & Installation
1. The Enclosure Assembly 📦​
Your kit comes with a protective box. Electronics hate water, and since this device lives next to your plants, we need to shield the "Brain" (ESP8266) from accidental splashes.
Step 1: Secure the Electronics
- Take the Mounting Board (the flat plate).
- Peel the adhesive backing off your Breadboard and stick it firmly to the center of the mounting plate.
- Use a small dab of hot glue or double-sided tape to secure the Relay Module next to the breadboard. Make sure no metal pins from the relay touch the other parts.
Step 2: Cable Management
- Pass the Power Adapter cable through the side slot of the box and plug it into your breadboard power module.
- Pass the Pump Wire and Sensor Wires out through the front slots.
- Gently tuck the excess jumper wires inside the box. Ensure no wires are pulled tight.
- Snap the lid onto the box.
💡 Pro Tip: Use a zip-tie to bundle the wires coming out of the box. This prevents them from being yanked out if someone trips over them.
2. The 3-Way Water System 💧​
Your kit includes a special 3-way connector. This allows one single pump to water multiple plants at once.
- Connect the output of the Water Pump to the main input of the 3-Way Splitter using the vinyl tubing.
- Cut three smaller pieces of tubing and connect them to the three outputs of the splitter.
- Important: Try to keep all three tubes the same length. If one tube is much shorter, water will take the easy path and only water that one plant!
3. Real-World Installation 🌻​
Now, let's take it to the plants.
1. Positioning
- Place the Water Bucket on the floor.
- Place the Enclosure Box on a shelf or table above the water level. (This prevents water from siphoning back into the box if the pump fails).
- Place the Soil Sensor into the soil of your most "sensitive" plant. Push it in until the gold contacts are almost buried.
2. Calibration in Soil Soil is different from a cup of water. You might need to adjust the sensor sensitivity.
- Power up the system.
- Look at the tiny lights on the Soil Sensor Module.
- If the soil is dry but the pump isn't running -> Turn the blue potentiometer dial Clockwise until the LED on the module lights up and the pump starts.
- If the soil is wet but the pump is still running -> Turn the dial Counter-Clockwise until the pump stops.
4. Safety & Maintenance​
- Refill the Tank: Don't let the pump run dry. Check your water bucket every few days.
- Sensor Corrosion: Over months, the metal prongs on the soil sensor might corrode (turn green). If this happens, clean them with sandpaper or replace the sensor input.
