Arduino manager ios6/12/2023 Temperature, atmospheric pressure, and approximate altitude were all sent over the BLE connection with an iPhone. The data being sent was read from a BMP280 sensor over the I2C port by the MakerBLE board. Using the BLExAR iOS app again, we were able to monitor the incoming data from the MakerBLE board, plot the values, and save them to a comma-separated value (CSV) file. This is the second entry into the tutorial series centered around the MakerBLE Arduino board. Adafruit invests time and resources providing this open source code, please support Adafruit andopen-source hardware by purchasing products from Adafruit! Written by Limor Fried & Kevin Townsend for Adafruit Industries. *************************************************************************** This is a library for the BMP280 humidity, temperature & pressure sensor Designed specifically to work with the Adafruit BMP280 Breakout -> These sensors use I2C or SPI to communicate, 2 or 4 pins are required to interface. Which will encompass a range of topics involving data collection, sensor peripherals (UART, SPI, I2C), message transmission,īLE peripheral/central communication, environmental monitoring, and other engineering and technology fundamentals. This will be the second entry in a series of tutorials ( click click here for part I) centered around low-power, BLE-enabled, portable microcontroller projects We will use the Arduino IDE and platform to program the MakerBLE and use existing libraries to read from the BMP280 I2C sensor. The BLExAR app will then plot the incoming data points for us to visualize and monitor over time. In this entry, the MakerBLE will use its I2C port to read ambient temperature and barometric pressure from a BMP280 sensor,Īnd transmit the results to the BLExAR iOS app. It will allow us to communicate with an iOS device and record data directly from a range of different sensors and peripherals. In a previous tutorial, we delved into the MakerBLE Arduino board, which isĪ low-power, tiny, Bluetooth Low Energy-enabled variation of the Thus, there is a need to test devices in new and novel scenarios where long cables, large equipment, big budgets,Īnd limited power availability, to name a few, are unrealistic and/or counterprouctive to the Prevalent in the integrated circuit industry [read more about integrated circuits here Electronics are still getting smaller and denser through advancements made in mechanical, chemical, thermal, and packaging methods The need for wireless datalogging is, at least in part, due to the increased use of portable devices and wearables in daily Wireless data collection still remains an innovative component in the development of electronics and new hardware technologies.
