Open fest 2019 WiFi mesh for monitoring and control of large areas
1 like377 views
WiFiWave mesh technology allows for monitoring and management of large areas through a self-organizing WiFi mesh network of ESP32 nodes. The technology is easy to install, potent, with fast and self-organizing dynamic networking that is a good fit for many applications demanding security and easy wireless expandability. Each node can communicate with any other node in the mesh and act as an access point or router to expand the network coverage.

- 3. Are you producing your boards in Europe? YES, we do! All production is done in Plovdiv, Bulgaria with 8 high speed assembly
- 5. Bulgaria is Leading in Open Source Hardware in Europe and is 2nd in the world after USA
- 6. Traditional WiFi ● Point to Point or ● Point to Multi Point ● All nodes connect to WiFi Router ● Routers has limits for the connected nodes ● Limited coverage
- 7. WiFi ESP32 mesh ● Self organize ● Self expanding ● Self managing ● Self balancing ● Each node can talk to any other node in the mesh and act as AP and router
- 8. WiFi ESP32 mesh II ● One node is elected as root and make the connection to outside WiFI AP ● If root is down new root is elected ● If nodes are disconnected the newtwork changes it’s internal routing dynamically
- 9. WiFi ESP32 mesh III ● Up to 100-200(?) m in one hop between nodes ● Up to 1000 nodes in one mesh (typ. 500) ● Up to 10 connections per node ● Up to 25 hops ● Up to 10Mbit transfer (typ. 2Mbit) ● 500 nodes build mesh in 30s ● Many mesh networks can co-exist ● Each Mesh have ID and PASS, Each node have MAC and NAME ● OTA firmware upgrade
- 10. WiFiWave – upgrade ESP32-mesh ● Add https and authentication when talk to the root from local network ● Add platform independent App for mesh configuration and programming via USB ● Add new node functionality, interfaces, drivers ● Add OLinuXino server for connections to outside world and data logging
- 11. WiFiWave node interfaces ● Digital Input → reflective, inductive, proximity sensors, switches, buttons ● Digital output → relay contacts ● I2C master → temperature, humidity, pressure, air quality, light, magnetic field, GPIO, DIO, AIO, RTC ● SPI master → LCD, LED displays, fast sensors, audio, video cameras ● Timer, Counter, Sunrise, Sunset
- 12. WiFiWave potential applications Industry 4.0 ● Machine data collection, store and analyze, patterns, decissions ● Machine monitoring and prevantive maintenance
- 13. WiFiWave potential applications Smart City ● Lighting ● Environmental monitoring ● Security ● Traffic monitoring
- 14. WiFiWave potential applications Home automation
- 15. Summary: WiFiWave mesh technology is easy to install and use, very potent technology with fast and self organizing dynamic networking. It’s good fit for many applications which demand for security and easy wireless expandability.
