One PAR reading is a moment. DLI shows the whole day.
AH-PARDLI tracks PAR throughout the day, calculates Daily Light Integral, keeps long-term light history, and lets you export the data for deeper analysis.
- Real-time PAR measurement
- Automatic daily DLI tracking
- Up to 180 days of history
- CSV data export
- Bluetooth app connection
- No internet required
Your plants do not experience one PAR reading.
Sunlight and grow-light intensity can change hour by hour. A single PAR measurement tells you what is happening at that instant, but it cannot tell you the total amount of photosynthetically active light the plant received over the day.
DLI solves that by integrating PAR over time.
Track how PAR changes from morning to evening.
AH-PARDLI records changing light conditions so you can see the daily PAR curve instead of relying on a few manual measurements.
- Measure current PAR in μmol/m²/s.
- Record all-day changes automatically after setup.
- Visualize the PAR curve to identify peaks, drops, and changing conditions.
- Use the trend to make better decisions about placement and lighting.
One day can be unusual. Trends tell you more.
Clouds, seasonal sun angle, shade, greenhouse structures, plant growth, and light schedules can all change the amount of light that reaches a canopy.
AH-PARDLI keeps up to 180 days of history so you can review DLI changes over weeks and months instead of guessing from memory.
- Review daily DLI history.
- Compare days and identify recurring patterns.
- Download data as CSV for your own records or analysis.
Start tracking daily light in three steps.
Place the sensor at the plant canopy, start the meter, and use the AquaHorti app to review full-day light.
Press to start
Position the sensor where you want to understand the actual light received by the plant.
Open the app
Connect by Bluetooth. Internet access is not required for the meter connection.

See current data, daily light history, PAR curves, and exportable records.
Measure where the leaves actually are.
The adjustable-height mounting approach helps you position the sensor near the plant canopy instead of measuring from an arbitrary location.
- Suitable for gardens, greenhouses, and grow areas.
- Adjust measurement height as plants change.
- Keep the sensor focused on the light environment that matters.
Export, compare, and understand your light environment.
Use recorded data to compare locations, days, lighting schedules, or seasonal changes instead of relying on impressions.
Connect locally. No internet connection required.
After Bluetooth permission is enabled for the AquaHorti app, the meter can connect directly to your phone without relying on internet access.
This makes the system practical in greenhouses, gardens, remote growing areas, and other places where Wi-Fi may be unavailable or unnecessary.
- Bluetooth connection to the AquaHorti app.
- Works without an internet connection.
- Designed for straightforward field use.
AH-PARDLI FAQ
What is AH-PARDLI designed to do?
It is designed to monitor PAR over time, calculate Daily Light Integral (DLI), store long-term light history, and let you export recorded data. Its main advantage is seeing how plant light changes across the whole day and over many days.
Why not just take one PAR measurement?
A single measurement only represents one instant. Light can change substantially during the day. DLI captures accumulated photosynthetically active light over time, which makes it more useful when you want to understand the plant's total daily light exposure.
How much history can it store?
AH-PARDLI can keep up to 180 days of recorded history for reviewing longer-term changes and trends.
Can I export the data?
Yes. Recorded DLI and PAR information can be exported as CSV data for further review and analysis.
Does the Bluetooth connection require internet access?
No. The Bluetooth connection itself does not require an internet connection.
Where should the sensor be placed?
For useful plant-light data, place the sensor at or near the canopy level you want to evaluate, with the sensing surface exposed to the same light environment as the plant.
Stop guessing from one reading.
See the light your plants receive all day.
Track PAR, calculate DLI, review up to 180 days of history, and export your data with AH-PARDLI.
