README
README.mdCompact BLE IoT Sensor Node
This IoT reference design is a compact BLE sensor node that features:
- Bluetooth Low Energy (BLE) wireless connectivity
- Array of real-time sensors
- Direct smartphone/tablet connectivity
- Coin cell battery for long life operation
- Small form factor
- JTAG programming access
The BLE SoC integrates an ARM Cortex-M3 to control the wireless transceiver and interface with the sensors. This design combines an ambient light sensor, a temperature sensor, and an accelerometer to enable applications such as building automation, industrial equipment monitoring, etc.
A software interface app to display and log data is included, and can be readily installed on any Android system with BLE capabilities. This app can communicate with and configure any sensor node within the communications radius. The app also provides estimates of the signal strength and remaining battery lifetime for each sensor node.
This compact BLE sensor node can be used in applications including:
- Real time sensing of ambient light and temperature for environmental monitoring and control
- HVAC systems and building automation
- Shock, vibration, and temperature monitoring of industrial equipment
- Theft, temperature monitoring of storage/shipping containers
This IoT Platform consists of:
- PCB design files for the KiCad v5.1.9 design environment.
- Source code and binary format firmware
- Android mobile app for data logging via smart phone
This project is provided as-is. Working samples (Alpha version) were created and tested successfully.
Prevents versions can be retreived by selecting the appropriate tag on Github at github.com/cmcmicrosystems/iot_platform
Versions:
