LoRa Experimental Environmental Sensors (LoRaXes) by ralphjy:
ralphjy 's project LoRaXes is a loose reference to a Dr. Seuss character in a book about the plight of the environment during the industrial age. He began building a pair of outdoor LoRa sensors to use for GPS, temperature/humidity/pressure, ambient light, water level, and PIR. He started his project to find a use for a Things LoRa Gateway and two MKR WAN 1300 boards that he won as the Grand Prize in the IoT: In the Cloud challenge. This was his first experience with LoRa and the Things Network.
- Connect gateway to Things Network - there were only five LoRa gateways within a 50 km radius of my location that were connected to the Things Network, so he added access for sensors near him.
- Build two portable battery operated sensor units - he only fully completed assembly of one of the units, but he's tested the electronics for both.
- Connect both units to the Things Network - he has unique applications running for each MKR Wan 1300 on the Things Network console.
- Provide GPS functionality for one of the units - the fully assembled unit has the GPS module and he has used it with the mapping integration on the Things Network to display the unit's location.
- Measure RSSI in the proximity of his house - units have good operational margin on his property.
Goals Not Achieved:
- Determine the effective LoRa range of he gateway/sensor setup - he needed to find the time to get some data walking the GPS unit away from the gateway. hHe should be able to correlate the RSSI data associated with the GPS data packets and use -120 dBm as a range metric (or he could guess the real metric is when packets are not received - use the last location received). His accuracy may not be that good if he doesn't do some averaging. He's noticed that over time he could get geolocation outliers of 50-60 meters even though the clustering is more like 5-10 meters (with the unit in a static location).
- Measure/optimize battery life - He sort of gave up on this one when he realized that he has older MKR Wan 1300 boards that do not power down the Murata LoRa module in sleep mode (fmilburn pointed out this issue). The achievable sleep mode current is ~2 mA. He's seen implementations of full power shutdown using the TI TPL5110 ultra low power timer. He thinks he will give that a try. He can make room on the proto board to handle that. And he'll need to make sure that the GPS handles save and restore of the tracking data correctly. His guess is that even with the newer MKR Wan 1300 (released the end of 2018) he would still have had to power down the GPS since its power save mode draws ~11mA. He may need to look at other GPS units.
- Determine the reliability of his system by analyzing uptime - this is difficult to quantify in the prototype stage since he's been constantly power cycling the units. He noticed that his gateway reboots at least once daily. He probably needs to automate some processing on the Things Network console.

This is a great project that demonstrates how you can solve a real world problem, for a $100 and some engineering know how. The Philadelphia Oil Refinery Explosion, was responsible for the shut down the largest and oldest oil refinery on the East Coast, and was a massive blow to the local economy. This event was the inspiration behind sjmill01 's Remote Monitoring & Control project, Big Petro Maker Magic: $100 Datalogger That Can Save Millions. It idea for The Fixed Equipment Vitals Megalogger was to have 24 sensors logging data every one minute and run without mains power or human intervention for 7 days with no wires. By taking Rosemount 648 Wireless Transmitters used for normal internal process condition monitoring, one can measure the fixed equipment vital conditions: Surface Temperature, Strain, Vibration, and Thickness. The Wireless versions of the Rosemount Wireless Transmitters make a great solution for temporary, freaky, intense, fixed equipment monitoring. Normally, control systems monitor what is in the pipes and vessels - not the assets themselves (with the exception of large furnace tubes and rotating equipment).

"I really liked this project. Sean explained it really well, and showed his steps of how he developed his project, and all code is published. The end product looks usable too." - Community Member Judge
"Sean did a great job of detailing this project and providing a solution to a real world issue in an innovative way. The end result is a very cost effective way to improve the safety and monitoring of pressurised systems." - Community Member Judge
"Entertaining video. Always a pleasure to follow them along on their journey." - Community Member Judge
"The project is the grand prize winner. Some impacting aspects of the project IMHO match the most important aspects of the philosophy of Project 14: it's open source (very welcome), and it's really original for the topic, the field of application and for the idead in general. Then the project is well done very near to a on-field testing prototype than just a proof of concept demonstration. As a chemis I can appreciate the value of this project in the chemical production plants." - Community Member Judge

Smarthab: Remote Sensing & Control by phoenixcomm:
From the start, phoenixcomm designed Smarthab with connectivity. Smarthab uses several forms of connectivity: Bluetooth, Zigbee,e WiFi, RFID, and Internet.
And here is what they do:
- Zigbee - Interconnection of low-power devices in a mesh network such as my thermostat or air quality management system.
- Bluetooth - Interconnection of devices that work in a higher power band, such as keyboards, room fobs (controller). to be designed
- RFID - Passive devices, 20cm for fobs and badges, etc.
- WiFi - Connects my cars to my house for updating Music, Phone Numbers, etc. This also lets Tablets, and Laptops on my network, via a RADIUS, Remote Authentication Dial-In User Service.
- Internet - Connects to the world wide web, via an OpenBSD Firewall. This firewall only connects via three cables two only with MAC address (Data-In and Data-Out). In this way, nothing looks like it's there ie. just a piece of wire. The third is normally on the motherboard and is used for back-end control.
She'll describe how her Smarthab monitoring and control will be accomplished.

CatDogFoxBot by dubbie:
dubbie has been blessed (or plagued) by wandering cats and the occasional fox in his back garden, so he decided to make something that would detect how often a cat (or other small animal) actually passes by. Having interest in the GridEye thermal array sensor he wanted to see if he could use a GridEye to detect these cats. The Grideye module was much smaller than he was expecting, although not a problem. For this project, he will also be using one of the step motors that he used in HoloPiBot #10 : It Actually Works - It Really Does! Having created a nice 3D printer holder for my DC motor mobile robot ( DCMotorsMobileRoBot #4 : 3D Printed PCB Holder, he decided to try and do the same for this project and he will be using another connectorless Nano. Having collected together all the parts needed to get started he sits down for a couple of hours using TinkerCAD to design some 3D printed parts to hold everything together. He's made the platform to hold the stepper motor and a widget to connect the Grideye PCB to the spindle of the stepper motor. For the initial design he used the parts in combination with some metal pillars a compact and a tidy module was produced. He demonstrates scanning the Grideye sensor backwards and forwards through 180 degrees. He makes the I2C connections between the GridEye sensor and the Arduino Nano. The specific GridEye sensor that he purchased did not seem to have any accompanying documentation, although it was claimed there was some on the supplier’s website but he could not find it. So, he decided that as it was a breakout board that most simple GridEye breakout boards would be pretty much the same so he used the Adafruit documentation and library. There was one problem in that the GridEye is a 3.3V device but the PCB he has just says Vin. After a close look at the PCB there does seem to be a voltage regulator so assuming they would have put 3V instead of Vin if there wasn't a regulator he connected it to the 5V supply from the Nano. The other I2C connections were straight forward.
"A nice study of how to not just collect data, but how to try to pull out useful information from it, to determine the presence of animals. It was a challenging project, and dubbie has done a lot of work to get this far. Very interesting to read." - Community Member Judge
