Active Projects
Mapon - Bank-Agnostic KHQR Network
Problem: Merchants need separate terminals for each bank's KHQR payments.
Solution: ESP32-based terminals validating transactions directly through Bakong blockchain. Works with any Cambodian bank.
ESP32 Bakong API KHQR
ACE - Clean Energy Stove Monitoring
Problem: Need to collect usage data from stoves deployed across rural Cambodia with no internet.
Solution: LoRa mesh network with ESP32 + SX1262 boards. 30-day battery life, Salesforce integration, mobile app for field workers.
LoRa Meshtastic Salesforce Flutter
Evola - BSF Manufacturing IoT
Problem: Manual tracking of insect farming production with no visibility into environmental conditions.
Solution: Digital scales, RFID crate tracking, environmental sensors (CO2, methane, temp/humidity) - all connected to Odoo ERP.
Odoo IoT RFID RS485 Raspberry Pi
Air Quality Monitoring
Problem: Limited air quality data availability in Cambodia.
Solution: ESPHome-based sensors collecting and publishing real-time PM2.5, temperature, and humidity data via AQICN.
