hellothing NB-IoT Arduino Shield
This is a library for the hellothing NB-IoT Arduino shield. For more information about the setup of the device and the library click here.
Temperature sensor - This is a basic example to display basic TCP/IP communication with the onboard temperature sensor.
Leak detector - This is a use case to build remote leak detection unit with the option of system control eg. A geyser with a flow valve. ** External hardware needed.
- A0 - Temperature sensor
- A1 - Modem current
- D2 - Button
- D3 - Accelerometer interrupt
- D8 - Modem 1.8V ok
- D9 - Modem enable
- D10 - Test LED 0
- D11 - Test LED 1
- D12 - Modem Rx
- D13 - Modem Tx
The shield is powered through the Arduino. The Arduino can be powered as normal either by the USB cable or an external power supply(7-12V).
