The Need
Our client, a leading Utilities company wanted to develop a NB-IoT enabled air quality monitoring solution with cloud connectivity. They wanted a solution that optimized battery life to run for years.
Impacts Delivered
- Smart Air Quality Analyzer with an NB-IoT chip that runs on the battery as well as USB
- Implemented Real-time monitoring of air quality with alerting if the air quality goes below permissible values
- Data is made available on the cloud for actionable insights.
- The extended battery life of 3 year
Our Solution
- Gadgeon developed an air quality Sensor with an NB-IoT chip that runs on battery.
- An ultra low power MCU will be the heart of the system.
- It will operate in sleep mode and wake up periodically to sense the air quality and store the readings in flash memory.
- Depending on the readings, it will configure the next sensing interval and go back to sleep.
- A replaceable battery of 2000mAH is used for the system.
- The device will run directly on USB power if available, otherwise, it will resort to the battery.
- The expected lifetime of the battery is close to 3 years.
- The readings are sent to cloud platform hosted in AWS. Users can log in and view their system status through a mobile app.
- In case of air quality alerts, push notifications are sent to mobile app.
- Users can view the history of the readings and get trend charts etc.
Why NB-IoT ?
- Moderate module cost, Ideal for high-density IoT applications
- Very low power consumption and hence extended battery life
- Extended long-range coverage and deep penetration indoors and underground.
- Easily integrates into existing cellular systems and easy deployment
