# IoT Monitor

Monitor sensors and track environmental data.

## Quick Start

### Read Sensor via HTTP

```bash
# Read from HTTP sensor
curl "https://api.sensorplatform.com/v1/sensors/lake_level_01/current"
```

### Read via MQTT

```bash
# Subscribe to MQTT topic
mosquitto_sub -h broker.hivemq.com -t "sensors/lake/level" -C 1
```

### Store Reading

```bash
# Log sensor data
cat >> ~/.sensors/readings.jsonl << 'EOF'
{"sensor_id": "lake_level_01", "value": 3.2, "unit": "meters", "timestamp": "2026-03-14T16:00:00Z"}
EOF
```

## Workflow: Lake Water Level

1. **Read**: Check lake level daily via HTTP/MQTT
2. **Analyze**: Compare to baseline (3.5m)
3. **Alert**: If level drops >0.5m:
   - Send Slack message via slack-notifier
   - Call owner via phone-caller
4. **Log**: Store historical data

## Supported Sensors

| Type | Use Case | Typical Range |
|------|----------|---------------|
| water_level | Lakes, tanks | 0-10m |
| temperature | Indoor/outdoor | -40 to 80°C |
| humidity | Basements | 0-100% |

## Alert Channels

- Phone call (critical) → phone-caller
- SMS (high)
- Slack (medium) → slack-notifier
- Email (low) → resend-cli

## Example: Smart Home

1. Temperature sensor reports 30°C
2. Check AC status
3. If AC off → Send alert
4. If critical (>35°C) → Phone call
