Since having built a simple testing rig on breadboard for interfacing TMP117 sensors with the MSP430 MCU, we've produced a PCB prototype to better evaluate possible LoRa radio solutions. After all, the purpose of the device is to autonomously report temperature readings wirelessly, while still having a fairly low power-consumption.
A simple testing setup for the TMP117 sensors attached to a ultra-low power MSP430 MCU with an FTDI for USB-TTL conversion. This will be used as a base-line for the power consumption and as test setup of the actual minimal setup to be designed as part of one of the HE4T use cases focusing on road-embedded temperature measurements.
Well... Neither had we until one of the screens we'd been working with accidentally broke and one of the specialists working Lapland UAS decided to see what made it tick. The unit in question can display not only black and white, but also red. Apparently the ink smelled wonderful.
The consortium convened for the second time, this time in Luleå, Sweden. The event was hosted by LTU. The interesting discussions were laden with technology and all-things energy harvesting. Future plans for the project were made and work were presented.
The webpages for the Interreg Aurora project HE4T are now published! On these pages we strive to release material, news and developments from the project as it progresses over its three year span. Developed solutions will be made public using this webpage.
