LoRa-Tooth

By ,

Designed BLE sensors and WiFi and LoRa gateways based on Nordic nRF51822 BLE modules and HopeRF’s RFM95W LoRa radios.  All wireless data presented as MQTT messages to a central broker, with integration into InfluxDB and Grafana for dashboards.  Features include

• Distributed WiFi and LoRa gateway architecture
• BLE-LoRa bridging
• BLE beacon replay/spoof detection
• Geolocation of BLE beacons in both WiFi and LoRa architecture
• small form factor sensor design for years of battery life on coin cell batteries
• Fun development process by using ARM mBED to manage complexity
• Low cost, accessible project
• Many practical sensor examples
