During transportation of goods there are several factors that contributes to damage of goods. It can be a deliberate act or accidental. But receiving party might not notice this unless opened while receiving the goods.
This project intends to provide an effective monitoring unit which can be used to monitor the container's health in terms of temperature, humidity, tilt and when and for how long the container was opened.
This system consists of various sensors attached to a single MCU with WiFi capabilities. Ideally, connectivity using 3G/4G module is suited for this kind of application. Since I have no 3G/4G module, for my prototype, I chose WiFi connectivity. Below are the components used in this project,
- Redbear's CC3200 WiFi Micro: This is the main entity responsible for collecting sensor data and posting it on to cloud.
- DHT22: This module is used to fetch real-time temperature and humidity inside container. This is connected to D2 pin of CC3200.
- MQ135: This gas/smoke used to monitor air condition inside the container. Analog out from MQ135 is connected to A1 pin of CC3200. ADC channel is 1.5v tolerant, so voltage divider is required as shown in schematics.
- MPU6050: This used to detect container tilt along x-axis. This module communicates over I2C.
- IR transceiver: This is placed near door so that whenever door is opened the IR will not be reflected back, hence detecting opening of door. This module
- EM-411: This is GPS module which is connected to CC3200's RX0 pin.
Idea is to build a configurable system which can be modified by user at any given moment within lifetime of the container delivery. To achieve this an android application is developed which has following features,
- Fetching and displaying real-time data which includes temperature, humidity, air quality within container, tilt and GPS coordinates.
- Using GPS coordinates, locating container on Google Maps.
- Configuring alert parameters which play role is alerting user by sending emails whenever certain limits are exceeded.
For this project, a new device type is created, LHMS_parameters. This device type is now public. Manifest of LHMS_parameters looks as shown below. The convention followed here is, suffix "rt" is for real-time data, suffix "alert_mail" is used by Artik cloud rules engine to send alert emails, suffix "value" and "threshold" for compare parameters used by Artik rules engine.
Below are few screenshots of android app. Welcome screen would look like below image,
When clicked on "Get Real-time data" would update screen as shown below.
Below is "Configure parameters" view.
Below is the screenshot of radiobuttons for enabling/disabling email alerts.
Below is the screenshot of real-time data viewed on Artik cloud charts.
Rules engine is configured to send mails of violations only if "alert_mail" parameter is set to "true". For door opening event there is no "alert_mail" parameter, this alert is sent whenever door is opened because this is event can be very harmful and dangerous.
Below is the video demonstrating the rich GUI which is simple to use and allows reconfigurability of parameters without much fuzz. Reception of "door open" alert can be seen in this video.
Necessary files building android app is attached. It has 4 "activity",
- MainActivity: Handles login and web view.
- WelcomActivity: Welcome screen, gives two options, "Configure parameters" and "Get real-time data"
- MessageActivity: Handles configuring parameters and updating Artik cloud appropriately.
- RTActivity: Fetches latest data from cloud and displays it. Also provides an interface to view container location on Google Maps.
This is just a showcase of what can be achieved using Artik cloud and its powerful rules engine. This project can improve on certain aspects such as logging data locally whenever the system fails to connect with the cloud due to bad network and push stored data whenever the connection with cloud is established.
