Digiten Water Flow Sensor FL408 with Particle Photons

This the sensor we are going to build in this exercise.

We will need the following hardwares:

• A Particle Photon, it will work with Argon too (Can be bought here)

• USB Data Cable

• Digiten Water Flow Sensor FL408 (Can be bought here)

• Jumper Wires (Can be bought here)

• Breadboard (Can be bought here)

• Soldering Kit (Can be bought here)

• Laptop or Computer

1. Connect the Photon and FL408 Sensor onto the breadboard as shown in the figures.
   

   • Connect the FL408 sensor as follows.

     FL408 <---> Photon  
     Red    <--------> Vin
     Black  <--------> GND
     Yellow <--------> D2         

2. Refer to to register the Photon Device with our Particle account.

3. Flash the script ‘STAPI_1_FL408’ to the Photon. Fill in the mandatory parameters accordingly. You can choose to leave the optional parameters to their default values.

   /*=============================================================================================================================================
   !!! MANDATORY PARAMETERS
   =============================================================================================================================================*/
   // Water sensor digital pin
   String thingDesc = "flow"; //DESCRIBE THE DEPLOYMENT
   int sample_rate = 10 * 1000; // how often you want device to publish where the number in front of a thousand is the seconds you want
   /*=============================================================================================================================================
   OPTIONAL PARAMETERS
   (this parameters only works when it is the first time registration of the device)
   (if the device is already registered, these options are ignored)

   //Description of the location
   String foiName = "na"; //THE LOCATION NAME
   String foiDesc = "na";
   //Define the geometry of the location. Geometry types from geojson is accepted. Refer to https://tools.ietf.org/html/rfc7946 for geometry types.
   String locType = "Point";
   String enType = "application/vnd.geo+json";
   //Define the location of the thing. If location is not impt, use [0,0,0] the null island position.
   float coordx = 0.0; //lon/x
   float coordy = 0.0; //lat/y
   float coordz = 0.0; //elv/z
