SENSOR DEVELOPMENT
An overview of our sensor development stages
On April 20th, we have officially started working on the development of our sensors. To ensure a structured and efficient prototyping phase, we have mapped out our development process into four key stages:
-
Stage 1: Peer-to-Peer Communication: Establishing direct LoRa links between the Heltec nodes and our gateway. This phase focuses on hardware pin mapping and ensuring stable, battery-powered data transmission;
-
Stage 2: Multi-Hopping (Mesh Networking): Integrating mesh networking logic using the LoRa library. This will enable our nodes to act as repeaters, extending the network’s range through self-healing data pathways;
-
Stage 3: Sensor Data Collection: Integrating the BME688 and gas sensors with optimized firmware. Our priority here is power management—specifically utilizing Deep Sleep modes—and ensuring efficient sensor data packaging;
-
Stage 4: Dashboard Data Exposure: Developing an MQTT dashboard. This interface will be crucial to visualize the collected sensor data and monitor real-time fire alerts effectively.
