Compost Temperature Sensor

Quality compost starts by controlling its temperature. Not by estimating it.

Plantae’s Compost Temperature Sensor measures the temperature directly in the core of the pile, where the greatest biological activity takes place. With real-time data, the composting process goes from empirical to controlled: you know exactly what phase the material is in and when you need to intervene.

How does it work?

Thermal control of composting from the first turning.

01

Installation in the pile
The sensor is installed integrated in a probe that is inserted directly into the core of the compost pile. It does not require wiring and transmits the data automatically to the receiving Hub via LoRa radiofrequency.

02

Monitoring of the thermophilic phase
During the aerobic decomposition process, microbial activity generates heat. The sensor records the evolution of temperature in real time, allowing you to precisely identify when the material has entered the thermophilic phase (45–70 °C) and how long it remains in it.

03

Turning decisions based on data
The optimal time for turning is when the temperature starts to drop due to lack of oxygen. With real-time data you can detect that exact moment, without waiting for visual inspection, and optimize both the turning frequency and the oxygenation of the material.
Plantae Manager

The composting process, visible from anywhere.

Sensor data are displayed in real time in Plantae Manager. From the dashboard you can:

  • View the temperature curve of the pile core over time.
  • Identify the phases of the process: mesophilic, thermophilic and cooling.
  • Configure alerts when the temperature drops below the thermophilic phase or exceeds the safety threshold.
  • Document the process with objective data for traceability and certification.
  • Access from PC, tablet or smartphone.

For any composting process that requires thermal control.

Composting on a farm

On farms that manage their own organic waste — pruning residues, crop by-products, manure — controlling compost temperature makes it possible to ensure sanitization of the material and obtain a final product that is stable and of high quality for field application.

Composting plants

In larger-scale facilities, continuous monitoring of multiple piles allows the process to be managed efficiently, to document the conditions of each batch for traceability and regulatory compliance, and to detect anomalies before they affect product quality.

Composting projects with certification

Certain organic farming or compost quality certificates require documentation that the material has reached and maintained sanitization temperature for the minimum established time. The historical data in Plantae Manager provide this documentation automatically.

Why temperature matters in composting

Temperature is not just another indicator. It is the main indicator.

During the aerobic decomposition process, microbial activity generates heat. That heat is the sign that the process is working: microorganisms are actively breaking down the organic matter.

The thermophilic phase: between 45 and 70 °C

This is the most critical phase of composting. At these temperatures, the material is sanitized: pathogens, weed seeds and undesirable organisms are eliminated. If the temperature does not reach this range, or is not maintained long enough, the final compost may not be properly sanitized.

The risk of overheating

Above 70 °C, microbial activity begins to slow down and nitrogen losses occur through volatilization. Detecting that point and turning the material in time prevents these losses and improves the final quality of the compost.

Turning at the right time

Turning serves to re-oxygenate the material and restart microbial activity. The optimal time is when the temperature starts to fall due to oxygen depletion, not when it has already dropped completely. With real-time data, that moment can be detected precisely.

FAQs

Frequently asked questions about the compost temperature sensor.

The sensor is installed integrated in a probe that is inserted directly into the core of the compost pile. It does not require wiring or construction work.
The sensor covers the range required for composting, including the thermophilic phase (up to 70 °C). Check with the Plantae team if you have specific range requirements.
Yes. Each pile can have its own sensor and all data are displayed on the same Plantae Manager dashboard, allowing you to compare the evolution of different piles simultaneously.
Yes. The historical data in Plantae Manager record the temperature of the pile core with a timestamp, which makes it possible to generate objective documentation on process conditions for compost certifications or audits.
