Having finally completed the building and soldering process, here’s a fairly detailed view of the schematics, made with Fritzing [1]: Throughout the posts, all parts have been covered in detail except for the toggle switch and different colored LEDs. The toggle switch comes in very handy, as it allows the user to take readings withoutContinue reading “Schematics – 21/08/2021”

I finished assembling the first prototype. All that’s left to do is hook up the MKR1500 microcontroller and continue working with the code. I’m still waiting on a fix for the Arduino board. In the meantime, I’ve tested to see if the box is really waterproof, so far no water has gotten into the interior.Continue reading “Device Assembled – 26/06/2021”

Concerning the SIM problem, I couldn’t obtain a NB-IoT (Cat-M2) SIM card, so I’ll just be using the LTE-M (Cat-M1) network for this project. The Cat-M1 network is probably the better choice anyways, because it’s used more frequently, the land coverage is larger and the connection is probably better since everyone relies on it. SoContinue reading “More Updates and Started Building – 22/06/2021”

Here is a quick 3D sketch of what the final product will most likely be similar to. The electronics will be encapsulated in a small box, which has three LEDs on the front, right beside a button. Upon pushing the button, the device will activate the sensors and take the necessary readings. The five sensorsContinue reading “Approximate Sketch – 25/05/2021”
