In the DiveIno parts post I mentioned that DiveIno has the following three modules:

1. Screen and microcontroller
2. Sensor module
3. Power module

The Assembly - Screen and microcontroller module post covered the first module in the list. Let’s see how the second Sensor module can be assembled!

Parts

You will need the followings:

• DS3231 RTC Module
• Adafruit TSOP38238 IR Sensor
• Adafruit Piezo Buzzer
• Straight Female Headers
• Straight Male Headers
• Stripboard - Continuous strips
• Solid core wires

Connections

All parts have to be soldered onto the Stripboard, which has continuous strips according to the following connection diagram:

The back side of the Stripboard has parallel continuous strips. The female header pins, which connect the Sensor module with the Arduino Mega microcontroller, have to be soldered onto this side of the board. On the picture below this is highlighted with the Microcontroller text:

The DS3231 RTC Module comes with female headers. The Adafruit TSOP38238 IR Sensor has male headers. The opposite headers are soldered onto the front side of the module:

The final assembled module will look like this:
