Environment pilot Full-stack engineer

Comprehensive environmental monitoring solution — serial/protobuf sensor ingestion with realtime dashboards for water and air quality trials.

Problem

Environmental pilots fail when sensor data stays trapped on USB serial logs. SWIMS unifies protobuf-framed sensor ingestion, Python realtime services, and TypeScript web views so field teams can monitor temperature, pH, dissolved oxygen, and salinity continuously.

What it covers

Protobuf SensorData frames over serial from edge acquisition
Python realtime ingestion with continuous generator pattern
TypeScript web console (swims-web) for live charts
Draft monitor modules for graphing and logger utilities

Sensor to dashboard

def get_continuous_sensor_data(self, serial_port='/dev/ttyUSB0', baud_rate=9600):
    with serial.Serial(serial_port, baud_rate, timeout=1) as ser:
        while True:
            incoming_data = ser.read(ser.inWaiting())
            if incoming_data:
                sensor_data = sensor_data_pb2.SensorData()
                sensor_data.ParseFromString(incoming_data)
                self.temperature = round(sensor_data.temperature, 2)
                self.pH = round(sensor_data.pH, 2)
                yield self
