Sending Multiple Values to Initial State using JSON

Sending Multiple Values to Initial State using JSON

Review

Review

Goal: Use JSON to send Multiple Values to Initial State at Once

• It is faster and uses less bandwidth to send multiple sensor in a single package
• We will use JSON to package all the data and send to Initial State
• The following examples are provided as a quick reference
• More detailed steps are described in the lecture

Reminder: Steps to Connect Argon and Initial State

1. Create account at https://initialstate.com
2. Create stream bucket at https://initialstate.com
3. Create an integration -> webhook on Particle console
4. Write firmware sketch and flash Argon

Creating JSON

• To create JSON data, it is recommended to use a library such as ArduinoJson or JsonParserGeneratorRK
• You can also use String variables to manually build the JSON data, but this can be tedious and error-prone so it is not recommended
• Instruction and examples for creating JSON with ArduinoJson

Exercise - Send Multiple Values to Initial State

• Generate random temperature and humidity
• Send to Initial State with one JSON value
