This module uses the Bluetooth GATT SDK to retrieve data from a Sensirion SHT31 SmartGadget Development Kit.
This sensor measures temperature and humidity in a room, and communicates using Bluetooth LE (SMART, Bluetooth 4.0).
Requirements:
- Python 3.4+
- Bluetooth GATT SDK for Python
- a Bluetooth LE (4.0) enabled adapter
Usage:
import smartgadget
sm = smartgadget.SmartGadget(adapter_name='hci0', device_mac='E9:28:88:82:2B:E2')
print("SmartGadget: Temperature (°C): %.1f" % (sm.temperature())
print("SmartGadget: Humidity (%%): %.0f" % (sm.humidity())
print("SmartGadget: Dew point (°C): %.1f" % (sm.dew()))See the documentation of the Bluetooth GATT SDK for info about device scanning and how to get the MAC address of the sensor.
Tested on a Raspberry Pi Model 3 with Raspbian 9.
See the gatt-examples folder for further details and low-level code.
