🧩 Screen-by-Screen Guide
Screen 1 — Real-Time Monitoring
Shows the live soil moisture and system status.
- Moisture % – current soil moisture level
- Battery / USB icon – power status
- Raw value – unprocessed sensor reading
Press OK to continue.
Screen 2 — Moisture Target (%)
Select the soil moisture level you want to maintain(0%-98%).
Suggested values:
- 86% – lightly moist
- 92% – ideal for most indoor plants
- 96%+ – for moisture-loving plants (ferns, tropicals)
Press OK to continue.
Screen 3 — Pump Speed
Choose how powerful the water pump should run:
- Low
- Medium
- High
Tip: High speed works best for long tubing or plants placed higher than the water source.
Press OK to continue.
Screen 4 — Watering Duration (Seconds)
Set how long the pump runs when the moisture drops below the target.
Maximum: 16 seconds
Recommended:
- 4–6 sec – small pots
- 8–10 sec – medium pots
- 10–16 sec – large or deep pots
Press OK to continue.
🌡️ Screen 5 — Calibration Wizard (Required!)
Calibration ensures accurate moisture readings.
PlantMate uses a 3-sample median filter, which removes spikes and electrical noise for stable results.
Press START to begin calibration.
Step 1 — DRY Calibration
- Leave the sensor completely in the air (dry).
- Press OK to scan.
- The system takes 3 readings, sorts them, and saves the middle value.
- A ✓ checkmark confirms a successful save.
Step 2 — WET Calibration
- Place the sensor into a cup of clean water.
- Press OK to scan.
- Median of 3 readings is stored.
- A ✓ appears when done.
Calibration is complete. Press OK to continue.
📊 How the System Works
After setup, PlantMate automatically:
- Measures soil moisture at regular intervals
- Compares it to your target
- Activates the pump if the moisture is too low
- Waters for your chosen number of seconds
- Resumes monitoring mode
The screen shows live moisture levels and pump status during operation.
🔋 Power Information
- Works with any 5V USB power source or power bank
- Extremely low power consumption
- Automatically sleeps when idle
- Press any button to wake the display
🧪 Tips for Best Accuracy
✔ Insert the sensor at a slight angle for more consistent moisture detection
✔ Wipe the probe clean occasionally
✔ Recalibrate every 60–90 days
✔ Avoid highly salty fertilizer mixes (these can skew readings)
🔧 Troubleshooting
Pump Not Running
- Check the pump power connection
- Make sure Pump Speed is not set to Low in long tubing setups
- Moisture target may be set too low (try 86-96%)
Moisture Reading Not Changing
- Re-run Calibration
- Ensure the sensor cable is firmly connected
Watering Unexpectedly
- The sensor may be near the soil surface
- The soil is too loose or too dry
- Electrical noise — fix by recalibrating
