Better circuit picture of the soil moisture project

Can you share the doubts?

my doubt  is how is the water module(sprinkler) wires are connected.. in the picture which is in the blog.. it is not clear.. and also the other modules connections are not clear.. can u pls upload a better picture.

Can you please clarify which specific project we are talking about? there are two/three projects dedicated to soil moisture sensing pointing the specific one would be very useful.

Thanks.

the project i am talking about is, soil mositure detection and aslo the values are updated to the thingspeak platform

if the moisture content is low then the sprinkler starts. can u plssss look into this!!!

I don't know if this will make any sense to you but here it goes.

1. Under the Circuit Diagram section we have our Schematic made with Fritzing also underneath that we have the practical test setup.

2. In the schematic, from left we have our soil moisture sensor which is connected to a driver board, preety much any soil moisture sensor comes with a driver board, example Soil Moisture Meter, Soil Humidity Sensor, Water Sensor, Soil Hygrometer for Ardunio (google search this).

3. Next, we have our relay board and the Node MCU board, if you download the Fritzing Schematic and zoom it a little you can clearly see the pin No. example relay board, SINGLE CHANNEL 5V RELAY MODULE 

4. Beside that we have our DHT11 sensor in blue, which is able to measure the humidity of the surrounding air.

5. and finally the the submersible pump (AKA sprinkler) is powred on/off with the help of the relay.
