Rooftop Garden and Lighting Automation by the Internet of Things (IoT)
Open accessAbstract
The project used IoT to monitor embedded devices and take appropriate action by passing instructions regulating objects through a web server interface.
Overview
AI snapshot
Written from the paper’s full text.
TL;DR
The paper presents a prototype IoT system for automating a rooftop garden’s watering and lighting using an Arduino Nano, soil moisture sensor, LDR, relay, water pump, and HC-05 Bluetooth module. It reports threshold-based watering and night lighting control plus a component cost estimate, but no quantitative performance evaluation or field trial.
Key findings
- The prototype links moisture and light sensors to an Arduino Nano; when the soil moisture reading is at or below 700, the moisture level is treated as acceptable, while a reading at or above 900 triggers automatic pump operation.
- An LDR detects day/night conditions and switches the garden lights on at night; Bluetooth via HC-05 allows a mobile device to manually start the pump and turn lights on or off.
- The estimated device cost is 2,241 BDT, or 26.36 USD, with listed component prices including Arduino Nano at 280 BDT, LDR at 200 BDT, moisture sensor at 120 BDT, water pump at 300 BDT, relay at 250 BDT, and HC-05 at 250 BDT.
- Hardware specifications reported include a water pump maximum flow rate of 120 L/h and average current draw of 220 mA, and an HC-05 Bluetooth module operating at 2.4 GHz with 3 Mbps modulation and dimensions of 12.7 × 27 mm.
Methods
- The work is a design-and-fabrication prototype: an Arduino Nano with ATmega328P microcontroller reads a soil moisture sensor and an LDR, then controls a relay-driven water pump and lighting, with HC-05 Bluetooth for mobile manual control.
- Development used Proteus for schematic capture, microcontroller simulation, PCB design, and 3D verification, and the Arduino IDE for programming.
- The main analysis is threshold-based control logic and a cost estimation table; no experimental dataset, sample size, field deployment, or statistical analysis is reported.
Limitations
- The paper does not state limitations in a dedicated section.
- Evident from the text: the results are limited to prototype description and threshold values, with no quantitative performance testing, water savings measurement, reliability data, or comparison against other systems.
- Evident from the text: Bluetooth range, connectivity robustness, and long-term operation are not evaluated, and the system is not tested in an actual rooftop garden trial.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
