SHT31 Air Temperature & Humidity Sensor with Particle Argon

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

We will need the following hardwares:

• A Particle Argon (Can be bought here)

• USB Data Cable (Should come with your Particle Argon)

• A SHT31 Sensor (Can be bought here)

• Jumper Wires x 4 (Can be bought here)

• Breadboard (Can be bought here)

• Soldering Kit (Can be bought here)

• Laptop and Smart phone

1. Connect the Antenna to the Argon as shown in the previous figure.
   

2. Solder the header to your SHT31. Follow the instructions here.
   

3. Wire up the Argon and the sensor as follows:
   a. Connect the Argon and SHT31 onto the breadboard as shown in the previous figure. Connect the 3x3 pin of the Argon to the VIN pin of the SHT31 sensor.

   

   b. Connect the Ground (GND) pin of Argon to the SHT31 sensor.

   

   c. Connect the Argon SCL pin to the SCL pin of the SHT31 sensor.

   

   d. Connect the Argon SDA pin to the SAA/RH pin of the SHT31 sensor.

   

4. Refer to to register the Argon Device with Particle account.

5. Flash the script ‘STAPI_1_SHT31’ to the Argon. Fill in the mandatory parameters accordingly. You can choose to leave the optional parameters to their default values.

   !!! MANDATORY PARAMETERS
   ================================================================================================================
   String thingDesc = "sht31 temp and humidity sensor"; //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 (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. 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

6. Go to the device events page. You will see the device is posting data every 10s.
