Built in Kampala  ·  FFT Signal Intelligence

Every field,
pump, and patient
deserves a signal.

PulseGuard applies frequency-domain signal intelligence to Uganda's most urgent problems — not data centres. Farms. Boreholes. Clinics. Forests. The same physics. A different purpose.

“Zero data is not neutral. It is a decision made by default.”

The Platform

The signal is the truth. Whatever the source.

PulseGuard's processing pipeline — built on Fast Fourier Transform analysis — converts raw sensor streams into frequency-domain signatures. Anomalies appear as spectral deviations before they become failures.

The physics is identical whether the signal comes from a motor bearing or a borehole pump. We changed the sensor. We changed the story.

Six Frontiers

The machine doesn’t matter.
The problem does.

The same FFT pipeline. Six different sensors. Six communities who deserve data they’ve never had.

◈
Agriculture
Maize doesn’t speak. Until now.
Soil moisture, temperature, and microclimate anomaly detection for smallholder farms. Detect drought stress and disease risk before yield loss occurs.

◯
Water Infrastructure
36,000 boreholes. None should fail in silence.
Vibration and acoustic signature monitoring for rural borehole pumps. Detect bearing wear and cavitation before the community loses its water supply.

Maternal Health
A signal a rural midwife can act on.
Wearable sensor data processed for fetal heart rate pattern anomalies and early labour distress — designed for clinics with no specialist on site.

Cold Chain
The produce is safe. Until it isn’t.
Temperature and humidity deviation detection in cold rooms and refrigerated transport. Alert before spoilage. Protect the harvest after the harvest.

Environment & Forest
The forest has a frequency. We listen for it.
Acoustic anomaly detection for illegal logging activity and early fire warning via thermal and smoke sensor fusion across protected forest boundaries.

Transport & Engines
The engine tells you everything.
Vibration signature analysis for boda-boda and small commercial engines. Detect wear patterns before breakdown. Cut downtime. Protect livelihoods.

The Process

Three steps. Seconds to insight.

STEP 01

Sense

Low-cost sensors attach to the asset. Data streams continuously via GSM or LoRa — even in areas with limited connectivity. Edge processing handles gaps.

sensor → ADC → buffer

STEP 02

Process

The FFT pipeline converts raw signals into frequency-domain signatures. Each reading is scored against a learned baseline. Deviations are classified by severity.

STEP 03

Act

Alerts delivered via SMS, mobile app, or dashboard within seconds of detection. The health worker, farmer, or operator gets actionable information — not raw data.
