Property damage and environmental damage is a major issue in the world today, and especially in a place like FLorida which is prone to several natural disasters like hurricanes, storms and flooding. We propose a solution which collects environmental data wirelessly without external power from remote locations so we can assess damage and potential damage from natural and man made disasters beforehand.
What it does
collects data (temperature, humidity, wind speed, pressure and other parameters if needed) using ad hoc mesh of sensing stations connected by LoRaWAN and powered off batteries. This data can be viewed on a dashboard and can be used to predict damage.
How we built it
For the hardware, we used a rfm95 module, a MTK3333 GPS module, BME680, and an EPS32. The code for the hardware is a mixture of a lot of things including the lora mesh library from nootropicdesign. This allowed us to have a mesh network pretty easily. We did modify the code to suit our purposes but the base was an amazing help.
Challenges we ran into
We first wanted to use the Arduino Nano 33 BLE Sense but we didn't realize that it doesn't support LoRa until halfway through so we needed to change the sensors to use what I have on hand and to use an ESP32.
Accomplishments that we're proud of
we have 2 working sensor stations we are located 100s of miles from each other and we pulled off the project
What we learned
remote working with sensors requires a lot of patience. I2C libraries on nano sense board need updates
