Process

Components used: Particle Argon, breadboard (generic), jumper wires, soil moisture sensor, 1K resistor, LED (generic), piezo, PIR Motion Sensor (generic).

Circuits assembled:  (shown below)

Challenges: 1. Difficulty setting proper timing for codes of different sensors. For instance, we need real-time updates of the sensors’ input data for timely feedback, while intervals are also needed to prevent publishing events too frequently(which may cause IFTTT to reach use limits).

2.Not familiar with the usage and sensitivity of the PIR sensor.

3. A proper design integrating different sensors into a progressive combination instead of being simply put together.

Solution: 1. Use the ‘if( last_published + 60000 < millis() )’ condition instead of ‘delay()’ to allow parallel processing of the sensor’s activity.

2. Go over a separate tutorial project to learn how the PIR sensor works.

3. An iterative process of letting different sensors ‘talk’ to each other to form an integrated system.
