Amphenol GE2102 Thermistor with Particle Photons

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

This guide is based on these materials:

• The GE2102 Sensors

  • source 1

We will need the following hardwares:

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

• USB Data Cable

• Amphenol GE2102 (Can be bought here)

• Jumper Wires x 4 (Can be bought here)

• Breadboard (Can be bought here)

• Soldering Kit (Can be bought here)

• Laptop or Computer

1. Connect the Photon and GE2102 Sensor onto the breadboard as shown in the figures.
   

   • Connect the GE2102 sensor as follows.

     GE2102 <---> Photon  
     Pin 1  ->--<--------> GND
     Pin 2  ->-|<--------> A0
         10Kohm|        
               |<-----> 3V3         

     

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

3. Flash the script ‘STAPI_1_GE2102’ to the Photon. Fill in the mandatory parameters accordingly. You can choose to leave the optional parameters to their default values.

   /*=============================================================================================================================================
   !!! MANDATORY PARAMETERS
   =============================================================================================================================================*/
   // the value of the 'other' resistor
   #define SERIESRESISTOR 10000    
   // What pin to connect the sensor to
   #define SENSORPIN A0
   
   String thingDesc = "liquid temp"; //DESCRIBE THE DEPLOYMENT
   int sample_rate = 1 * 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

4. Refer to to visualize the data on Grafana.
