1
00:00:00,660 --> 00:00:09,930
One of the problems that I've noticed in the previous iteration of this course is that the moisture

2
00:00:09,930 --> 00:00:16,740
sensor that are used that corroded very quickly once it was inserted into the wet soil.

3
00:00:17,190 --> 00:00:20,900
So within a couple of weeks, the electrodes started to corrode.

4
00:00:20,900 --> 00:00:23,370
Then, of course, the sensor stopped working.

5
00:00:23,790 --> 00:00:29,400
So I found a better moisture sensor for the soil, which is this one.

6
00:00:29,400 --> 00:00:31,890
This is a capacitive moisture sensor.

7
00:00:32,250 --> 00:00:39,750
This particular model is from Sage Studio and I used that to replace the original sensor.

8
00:00:40,560 --> 00:00:46,260
I don't need this component anymore, which is just the amplifier because everything now is on the same

9
00:00:46,260 --> 00:00:55,170
unit and it's using a groove connector, which means that I use jumper ways to connect it to my PC be

10
00:00:55,170 --> 00:00:55,950
bought here.

11
00:00:56,880 --> 00:00:58,080
That was one issue.

12
00:00:58,080 --> 00:01:03,240
That was the quality of the sensor that I originally used that wasn't good enough.

13
00:01:03,240 --> 00:01:08,520
And now this capacitive sensor is much longer lasting.

14
00:01:08,520 --> 00:01:10,950
So I'll be using this going forward.

15
00:01:11,460 --> 00:01:16,720
Another problem that I had was just the jars full of soil with soil on my desk.

16
00:01:16,720 --> 00:01:21,780
It just wasn't a very easy set up for me to to work on this project.

17
00:01:22,230 --> 00:01:25,020
So I decided to go with an alternative.

18
00:01:25,230 --> 00:01:31,770
Remember that all all I need to do here is to just take measurements from moisture sensor, solar moisture

19
00:01:31,770 --> 00:01:32,310
sensor.

20
00:01:32,640 --> 00:01:38,220
So I went into the kitchen and got a couple of sponges.

21
00:01:39,210 --> 00:01:42,690
They are you can put a little bit of moisture in them.

22
00:01:42,690 --> 00:01:44,490
Just a few drops of water would be enough.

23
00:01:44,520 --> 00:01:54,750
Then create a sandwich, use a rubber band to keep two sponges together and insert the moisture sensor

24
00:01:54,750 --> 00:01:55,710
in like that.

25
00:01:55,710 --> 00:01:57,060
And that's basically it.

26
00:01:57,060 --> 00:02:04,290
That's enough now to provide me with all the sensing and data that I need in order to work on my note

27
00:02:04,290 --> 00:02:05,550
read flows.

28
00:02:05,550 --> 00:02:12,720
And you can see that as I was inserting and removing and then putting back the sensor into my sponge,

29
00:02:12,990 --> 00:02:18,630
did free set up the widgets in my dashboard or reactor putting green.

30
00:02:19,170 --> 00:02:28,200
So for any new lectures that I record from this point on which and now in January 2022, right after

31
00:02:28,200 --> 00:02:36,510
I upgraded my node change instance to version 2.15, I will be using this set up for my experiments

32
00:02:36,510 --> 00:02:40,530
instead of the jar full of dirt that I used previously.
