I'm looking for a team to work on a startup with this characteristics: IoT platform designed for continuous monitoring of biometric variables in industrial and high-risk environments. The objective is to strengthen occupational safety and facilitate informed decision-making through: • Wristbands (Wearables): Equipment for capturing vital signs (heart rate, oximetry, optional GPS). • Gateways: Devices configured with communication protocols (BLE, LoRaWAN, 4G, satellite). • IoT Platform: Environment for data management (ThingsBoard or equivalent), with Dashboard, alerts and initial analytics. It also includes the following requested extras: • Environmental Sensors: Optional integration in the Gateways to monitor conditions such as temperature, humidity and dust Phase 2: Firmware Development for Gateways • Programming of firmware, drivers and protocols (BLE, LoRaWAN, WiFi, etc.). • Stability and scalability testing in the laboratory. • Technical reference documentation. Deliverables: Functional firmware, laboratory validation report Phase 3: Configuration and Integration of the IoT Platform • Implementation of the platform (ThingsBoard or other). • Creation of control panels, alerts and security (TLS, user roles). • Testing data transmission from the Gateways to the server. Deliverables: Platform in operation, Dashboard and alert rules, architecture documentation.
