Project description:
"I need a full-featured mobile application that connects to temperature sensors and handles data coming from both indoor and outdoor environments. The core idea is simple: capture every reading, display it in real time, store it securely, and take action whenever a threshold is crossed.

Here is what I’m aiming for:
• Real-time monitoring with a clean dashboard showing current, minimum, and maximum temperatures.
• Continuous recording of every data point in a cloud database I can query later for reports or export as CSV.
• Instant alerts—push notification, email, or SMS—whenever the temperature rises above or falls below user-defined limits.
• Seamless integration with other devices or systems over Bluetooth, Wi-Fi, or an open REST API so the data can be shared or acted on elsewhere.

You’re free to propose the most suitable tech stack, but I expect a cross-platform solution (React Native, Flutter, or similar) plus a lightweight backend (Firebase, AWS Amplify, or another scalable option). Sensor data will arrive via standard protocols (BLE, MQTT, or HTTP), so experience with any of these is a plus.

Acceptance criteria:
1. Mobile app installs and pairs with a demo sensor within minutes.
2. Live temperature feed updates with no noticeable lag.
3. Alerts trigger reliably at user-set thresholds and are logged.
4. Historical data can be viewed and exported.
5. API documentation supplied for third-party integrations.

If you’ve delivered IoT or environmental monitoring apps before, let’s talk specifics and timelines." (client-provided description)
