Description
A Moisture sensor measures the volumetric water content in soil.
Block description
This block can be used receive analog inputs (% values in the range 0 to 100%) from an external moisture sensor connected to any of the ports S1, S2, S3.
Hardware interface
Connecting an external moisture sensor
Note: While connecting an external sensor to the Cloudio board, care must be taken to match the polarities of the sensor with that of the port (S1/S2/S3) that it is being connected to.
App interface and usage
Port :
Here, you can select the port the sensor is selected to - S1/S2/S3.
Operator:
Here, you can select the operator to be used while comparing the values received from the sensor against the threshold value set in the next step.
Value:
You can set an integer value in the range 0 to 100 for comparison.
You can use the Read option to read/receive real-time values from the port selected.
After you set the parameters for the block, you can press Done to confirm and save your changes.
Example
- The below project snippet turns the LED red if the reading from the moisture sensor is less than 30%, yellow if it is between 30% and 50%, and green if it is greater than to 50%.
Note: This is a code snippet to explain the working of the block. In this case, this code will be executed once and at the time of uploading the code.
You will need to use this snippet inside a loop infinitely block if you want this code to run on the board for the entire duration that the board is on.
