This is a small prototype car that uses an ultrasonic sensor so a car will turn to avoid hitting a wall with a remote on off capability.

The purpose of this project is to detect motion in the driveway and alert the user inside the house.

This project uses two argons to turn on an LED light when a water level sensor senses water in a cup.

Parking Sensor using an Ultrasonic Sensor and Particle Argons.

With the utilization of particle argons and sensors, we have constructed a reversing vehicular tool!

To prevent burn injuries from hot appliance.

To monitor user safety, a sensor cluster collects and graphs data of obstacles in the blind spot, wheelchair speed, and degrees of tilt.

The device will indicate the temperature inside your refrigerator/freezer in Celsius and Fahrenheit.

Use Particle Argons, Blynk IoT app, and a motion sensor to activate and change colors of an LED light strip.

Using a Particle Argon and a motion sensor I created a device that sends me a message whenever someone enters the house.

This will alert you when the gate is open so you can go close it.

A simple device to detect entry into such a storage room like a pantry with only one entrance.

A sensor that detects rain.

My neighbors are making a lot of noise with construction and I want to see when they are loudest so I can plan accordingly.

Using a metal touch sensor, I've essentially made a button that notifies the user when it's been released over a certain time threshold.

Have overzealous gamer siblings? Are YOU the overzealous gamer in your house? Detect and get notified of game-induced rage.

A home-based disaster detection and monitoring system for fire, flood, temperature, and humidity.

The way out of the one-way street.

Simple temperature sensor project used to collect temperature data on an OLED display.

Use DFRobot's UART fingerprint scanner to store fingerprints and only allow authorized people to access the box.

Use RedBear Duo to read from a sensor array and report data to the Particle Cloud.

Use IFTTT to automatically log data to a Google spreadsheet using a Particle Photon. This will show how I logged temperature data.

The Stinker Blinker will detect whether the bathroom door is closed/open and will turn a siren on/off to indicate vacancy.

Read multiple sensors from a Particle Photon and Publish via webhook to Thingspeak.
