Thank you for digging into the gadgets and sharing the valuable information. This kind of exercises helps in learning about the existing and new sensors. For example I did not know about BMP180 (barometric pressure sensor). Visiting the website of Bosch again I learned that they offer another one in the same line card - BME280, which is a Barometric Pressure, Humidity and Temperature sensors integrated in a small eight pad package with SPI/I2C interface.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
