Smart Compost Fermentation Monitoring for Quality Control in Taiwan

Corrosion-resistant temperature probes measure multiple depths inside compost piles, giving operators visibility into internal heat layers while reducing repeated manual checks in hot, humid, corrosive conditions.

Project Profile

• Region: Taiwan
• Category: Agriculture
• Products: S09-ST

Reference Impact

• Multi-Depth — Internal pile heat-layer visibility (Fermentation core)
• Anti-Corrosion — Long-term operation in hot, humid, acidic conditions (Environmental fit)
• Est. 20% — More consistent fermentation batches (Estimated improvement)

Case Snapshot

Heat, humidity, and acidity — that's the daily reality inside a composting operation, and exactly the conditions that make it hardest for staff to stay and take manual readings. Fermentation quality depends on keeping internal temperature within a target range, but the heat layers at different depths are difficult to track by hand. A large Taiwan composting site switched to S09-ST anti-corrosion temperature sensors placed at multiple depths, so conditions that were previously invisible are now data the team can follow continuously.

Problem

Heat Deep Inside the Pile Stays Invisible

Inside a large compost pile, temperature can shift quickly with aeration, turning frequency, moisture, and feedstock condition. If a pile overheats, turns anaerobic in pockets, or drifts outside its target range for too long, the result can be odor complaints, delayed fermentation cycles, and inconsistent fertilizer quality.

Manual measurement is not only time-consuming but also unable to capture variation across piles and depths at the same time. The heat, humidity, and acidity of the environment make it hard for staff to stay long enough to take repeated readings, so problems are often found only after quality has already suffered.

Solution

Multi-Depth Probes Map the Pile's Heat Layers

The site adopted S09-ST anti-corrosion temperature sensors, built for the acidic, high-heat conditions inside a compost pile and able to keep operating over time without corrosion damage. Sensors are placed at different depths to capture temperature distribution and fermentation changes, with data sent wirelessly back to the operations team.

This removes the burden of repeated cabling and manual sampling across a large site, and keeps heat-layer data current rather than relying on the occasional spot check. Staff can use live readings to adjust aeration, turning schedules, and moisture control in line with what the pile is actually doing.

Value

Temperature Data Grounds Every Adjustment

Inside the pile, conditions are hot, humid, and acidic enough that staff can only take a manual reading a few times before conditions become unbearable — so drift often isn't noticed until odor complaints start. With temperature now visible continuously, staff turn, aerate, or adjust moisture faster, catching drift before it affects output.

The site manager no longer has to send someone into the heat to take a reading by hand — pulling up the log is enough to confirm which batch actually hit its mark.

Next Step

Provide pile dimensions, target measurement depths, and site conditions to confirm material suitability, probe placement, and installation approach before defining a pilot.
