Now that I have the weatherstation working on a breadboard, it's time to solder it onto a protoboard for a more permanent solution.
Components
- Protoboard. Can be of any type. I used this, which has rails and smaller nodes, making soldering much easier
- BMP180 breakout board
- DHT22 temperature sensor
- 433 MHz transmitter
- MSP430G2553 microprocessor
- 20-pin DIP socket
- 47 kΩ resistor
- Battery holder for 2 D batteries
Schematic
Connect and solder components are shown in the schematic. Note that the "TI Launchpad MSP430G2" is actually just the 430G2553. So, it must be removed from the launchpad board. When using the chip without the Launchpad, the chip is powered from pin 1 and grounded from pin 20. In addition, pin 16 must have a signal to prevent the chip from resetting.
Conclusions
Because the 430G2553 is attached with a DIP socket, it can be easily removed from the board and reprogrammed as needed. Essentially, the weatherstation's components are set, but can still be programmed and tweaked as needed.
Next, the programming of the weatherstation.
