T.R.E.E Group
T.R.E.E. Group is an engineering and technology startup developing sustainable, autonomous solutions for agriculture, rural communities, and the environment.
We combine mechanical engineering, electronics, sensor technologies, autonomous energy, data science, AI, and software to turn real-world challenges into practical solutions.
Our goal is to create reliable technologies that can operate in areas with limited infrastructure and contribute to a more sustainable and connected future.
T.R.E.E Group builds battery-free, energy-autonomous hardware that turns ambient kinetic energy — wind, rain, vibration — into reliable, low-power monitoring and action for agriculture, even in areas with limited infrastructure.
SmartFertilizer is a standalone, battery-free hardware node that brings precision fertilization to fields with zero external power — running entirely on wind, rain, and crop vibration through a piezoelectric energy-harvesting system.
SmartFertilizer is a fully autonomous soil enrichment system engineered to deliver continuous land conditioning without manual intervention or external power connections. By combining a 3D-printed physical structure, an integrated refillable fertilizer container, and a self-sustaining micro-energy harvester, it solves the challenge of maintaining active soil saturation in remote or off-grid environments.
To guarantee zero-maintenance power for onboard sensors and release mechanisms, SmartFertilizer uses a two-part environmental energy converter, both feeding a single flexible piezoelectric strip (LDT0-028K) sealed safely inside a dry mast:
A dedicated energy-harvesting chip (LTC3588) stores these micro-charges in a supercapacitor. Once enough energy has built up, the system briefly wakes from deep sleep, reads a soil moisture or acidity sensor, and — only if the soil actually needs it — releases a precise micro-dose of fertilizer through an ultra-low-power actuator, such as a bistable solenoid valve, gravity doser, or piezo micro-pump. The system then returns to sleep and the cycle repeats.
A refillable core container houses an optimised nutrient release system that steadily enriches the surrounding soil. Its structure allows quick maintenance cycles while ensuring continuous, controlled nutrient flow directly into the root zone.
The housing is engineered specifically for FDM/SLA additive manufacturing in weather-resistant materials such as PETG or ABS, with built-in mechanical tolerances (0.3–0.5 mm) for print-in-place joints and hinges — eliminating the need for complex assembly hardware.
Following a frugal-innovation approach, the first working prototype is designed to be built almost entirely from off-the-shelf components:
| Component | Est. cost | Purpose |
|---|---|---|
| Energy harvester (LTC3588) | 25–40 AZN | Power-management chip converting piezo current into usable charge |
| Supercapacitor | 3–7 AZN | 1–5 F, 5.5 V buffer for storing harvested energy |
| Low-power microcontroller | 5–8 AZN | ATtiny85 / MSP430-class chip, microamp standby draw |
| Actuator | 5–12 AZN | 9 g micro-servo or pulse valve for the dosing gate |
| Soil moisture/acidity sensor | 2–5 AZN | Analog resistive or capacitive probe |
| Piezoelectric element | 0 AZN | Reuses the existing proprietary harvesting mechanism |
| Total prototype cost | 40–72 AZN | Average build: ~55 AZN |
