Satipo, Amazonian Peru 🌿

Predictive AI That Acts
Before the Mosquito Does

The first IoT + AI system built by Amazon students to predict dengue larval risk and automatically deploy Bti — a WHO-approved biological larvicide — before mosquitoes emerge.

How DengueStop Works

From sensor to action in 5 steps

1
🌡️
SENSE
DHT22 sensor reads temperature + humidity every 60s
2
🧠
PREDICT
AI model compares live readings to 4 years of SENAMHI historical climate patterns from Satipo
3
⚠️
DECIDE
If T° ≥ 25°C AND HR ≥ 70% sustained for 30 minutes: HIGH RISK confirmed → trigger deployment
4
💧
ACT
ESP32 activates micro-pump → releases 1mg/L Bti into water container automatically
5
🦟
ELIMINATE
Bti destroys larvae by ingestion in 24–48h. ⚠ NOTE: Bti acts ONLY on larvae — NOT on eggs or pupae. We disclose this limitation openly.
Responsible AI

We disclose what our system can — and can't — do

Risk Identified

False positives may trigger unnecessary Bti release. False negatives may miss real outbreaks due to limited local training data.

How We Manage It

Students physically inspect containers weekly using a standardized field protocol (IR% calculation). AI recommends — humans confirm before any large-scale deployment.

Human in the Loop

Community health workers review the dashboard weekly. Families decide whether to install the device in their home. The AI never acts alone.
