Developing smart sensor solutions

Developing smart sensor solutions

Ken Boak has published a new build, the MSP430i2041 bluetooth smart sensor board:

One of our existing products at work, which I designed about 2 years ago, makes use of the STM32F373 microcontroller interfaced to an AD7767 24-bit sigma-delta ADC, to create a smart sensor.
Whilst at the time of development, (Feb 2014) – this seemed to be an economical solution, our requirements have changed a little, in that we wish to add Bluetooth Low Energy Connectivity, LiPo battery support and the means to drive an OLED display. These functions could be added in the form of an additional pcb (similar to the Arduino shield concept), and provision had been made to accommodate such a board with an expansion connector, but after reviewing all of the costs, it was decided that a new approach – and a new dedicated pcb design would be ultimately preferable.
