Parts Connected to the PCB
The printed circuit board (PCB) contains all of the circuitry needed to run the sensors and to log data to an SD card. We have used the following company (Power Design Services) to build PCBs. Boards can be purchased with components already soldered on, or the boards can be purchased first, and you can solder the additional components (e.g., voltage regulator, temperature and relative humidity sensor, headers, etc.) on after receiving the boards. Components connected to the PCB are as follows:
