Since the LoRa-E5 Sponsorship with Seeed Fusion campaign launched, designers and engineers from all over the world have enthusiastically participated in it, we’re gladly received a wide range of interest and great feedback from the community. Moreover, we’ve been delighted to witness the successful and meaningful projects that many designers have made. Here are some case studies that have been made by various participants.

Case Study 1 – Solar-Powered Outdoor Air Quality Monitor transmits data over LoRaWAN

Gerrit Niezen from the United Kingdom, realized the seriousness of the environmental problem early on and started to take action to make efforts to solve it. He was looking for LoRa modules with LoRaWAN built-in. Seeed Studio’s LoRa-E5 is the one of the first modules that uses the STM32WL, which contains both a microcontroller and LoRa RF in the same chip. It comes preinstalled with a LoRaWAN stack, so it was very easy to integrate into the air quality monitor.

At the same time, Gerrit was also kind enough to share his thoughts after trying the Seeed Fusion PCBA one-stop service.

I bought my first batch of LoRa-E5 modules directly from their web shop, and they arrived relatively quickly. For my second prototype revision I used Seeed’s Fusion PCB assembly service, as Seeed currently has an offer for two free PCBA boards if it contains a LoRa-E5. I thought it was too good to be true.

During the design check Seeed even found a footprint issue that wasn’t discovered by other manufacturers during the first prototype run, and where parts were out of stock Seeed worked with me to find suitable alternatives. Seeed Fusion is such a reliable and convenient one-stop prototype service that I’d love to work with them again”.

Case Study 2: Low-Power Snow Depth Sensor Monitoring for IoT Smart City Based On LoRa-E5 Applied in Norway

As the Civil and Structural Engineer Todd Fratzel wrote in Maintenance, Roofing, Safety: “Each year heavy snowfall is responsible for severe damage to homes. Deep snow can cause structural damage and water damage. In addition, deep snow can cause carbon monoxide poisoning and serious fall injuries.” Thus, effectively monitoring the accumulated snow cover over time can facilitate the road traffic, expressway, aviation industry and meteorological personnel to better understand the meteorological disaster caused by snow cover, and to make corresponding prevention plans to ensure the safety of people and property.

Eivind Holt, a software developer in the field of e-health, used a Seeed LoRa-E5 mini (STM32WLE5JC) Dev Board and a MaxBotix Inc. HRXL-MaxSonar MB7374, and made a Low-Power snow depth sensor device that can measure how much snow has accumulated on the ground. It is able to run on small batteries for years, survive sub-zero (Celcius) temperatures and uses LoRaWAN to transmit measurements to the internet for further processing. The device has a watertight enclosure 3D-printed with resin SLA, and it has been applied to real uses for a month now with an achievement of 2600 transmitted measurements. The project even got an coverage on a local newspaper Norwegian, and several municipalities have shown interest in adapting the device to their specific scenarios. In the upcoming future, our team will join Eivind to explore how our Fusion prototyping and customization services can help scale up the project.

Case study 3: Former Ph.D Researcher At OSU Developed Stream Runoff Monitoring Sensors Using LoRa-E5 to Measure The Temperature, Quality and Flow

“Changes in streamflow can directly influence the supply of drinking water and the amount of water available for irrigating crops, generating electricity, and other needs. In addition, many plants and animals also depend on streamflow for habitat and survival.” the United States Environmental Protection Agency mentioned in a report “Climate Change Indicators: Streamflow”.

This is exactly the reason why William Dillon started a project many years ago to develop cost-effective sensors to measure the quantity, temperature, and quality of stream runoff over the course of a year with the support grant from the GEOLOGICAL SURVEY, UNITED STATES DEPT OF. And now William is taking the project further along with a friend and colleague by applying Seeed LoRa-E5 to make it possible to have a low-power communication with many years of battery life!

“Science for a changing world, technology for a better life! ”William and his team are the epitome of this USGS Slogan as he said, “I’ve been working on it as much as I can on weekends and at night because I believe in improving our environment as much as we can. I believe we can only succeed in improving the environment by understanding it, and measuring it.”

Case study 4: Monitoring Indoor Air Pollutants – The Silent Issue for Smart City IoT using Seeed LoRa-E5 and Fusion PCBA

During the Covid-19 pandemic, most people were forced to spend a lot more time at home and might be unaware of how the air that they breathe might influence their well-being. A polluted room or house can lead to irritation of eyes, headaches and long-term exposures can lead to respiratory diseases or even cancer.

This project is intended to provide an insight into the air quality within a room or house or even office, making use of an IAQ sensor with AI capabilities. This sensor uses a “breath-VOC” mixture to detect exhaled human breath and it measures the concentration of volatile organic compounds, using the BSEC 2.x library to output an IAQ. This could alert the user to let’s say open a window or if the conditions are extreme, look into purchasing an air purifier.

The final year student Mircea-Iuliu Micle at the University of Plymouth UK, after a long search of integrated packages or MCU + RF trans receivers combos, the Seeed LoRa-E5 choice was easy. It provides the LoRa RFIX(SX126X) with the STM32WLE5JC MCU on a single module, providing high performance and low energy consumption in a tiny package. On top of this, all it needs it’s 2 capacitors and an antenna!

With plenty of peripherals and memory available, the module is also capable of running Arm’s Mbed Os ( https://os.mbed.com/mbed-os/ ), making it a perfect choice for rapid prototyping and IoT.
