Spore

Problem

Fusarium wilt is difficult to confirm early in the field without lab turnaround. Spore explores a portable bench diagnostic: a microcontroller reads analyte-specific sensors, runs a lightweight detection routine, and shows pass/fail guidance on a local display for extension workers and student researchers.

What it covers

• Arduino-based acquisition with I2C display for operator feedback
• Sensor front-end tuned for Fusarium oxysporum screening workflows
• Serial logging for lab notebooks and repeatability trials
• Portable enclosure concept for barangay-level extension visits

struct AssayReading {
  float signalMv;
  float tempC;

AssayReading runFusariumScreen() {
  const float signal = readDifferentialProbe();
  const float temp = readThermistorC();
  const bool suspect = signal > kFusariumThresholdMv && temp < kMaxAssayTempC;
  oled.print(suspect ? F("SUSPECT") : F("CLEAR"));
  Serial.printf("signal=%.1f temp=%.1f\n", signal, temp);
  return {signal, temp, suspect};
