🎙️ Want to learn how IoT can make donation-bin operations safer, smarter, and more efficient? Listen to the full episode of our Solving with Sensors podcast to learn how connected sensors can monitor fill levels, detect tipping or falls, and provide early fire alerts.

 

Donation bins make giving simple. A donor can drop off clothing, shoes, household goods, or other needed items at a convenient location without having to coordinate with a staffed facility. For nonprofit organizations, these bins can extend their reach, increase collection capacity, and help keep reusable materials in circulation.

But every additional bin also becomes another remote location that must be managed.

Is it nearly full? Does it need to be collected today—or could that trip wait? Has the container been knocked over, moved, or damaged? Is an unusual rise in temperature creating a potential safety concern?

Without remote visibility, donation centers often have to answer these questions through fixed collection schedules, phone calls from property managers, or in-person inspections. That can lead to unnecessary trips to half-empty bins, delayed pickups from high-volume locations, overflowing donations, and slower responses to safety or vandalism concerns.

Embedded Works is helping federally recognized 501(c)(3) nonprofit organizations replace that uncertainty with actionable data. By equipping donation bins with connected sensors, their teams can remotely monitor three critical conditions: fill, fall, and fire.

• Fill supports collection planning and capacity management.
• Fall supports asset protection and faster response to tipping or interference.
• Fire supports earlier awareness of a potentially dangerous temperature event.

 

Donation Collection Has an Important Role in the Circular Economy

The need for more effective textile collection and reuse is significant. According to the U.S. Environmental Protection Agency, the United States generated approximately 17 million tons of textile waste in 2018—equal to 5.8% of all municipal solid waste generated that year. Only 14.7% of those textiles were recycled, while landfills received approximately 11.3 million tons.

More recent federal analysis shows that this is not a short-term problem. In a December 2024 report, the U.S. Government Accountability Office reported that EPA estimates indicate textile waste increased by more than 50% between 2000 and 2018. The GAO also identified limited, decentralized collection and sorting systems as one of the factors complicating textile recovery in the United States.

Donation bins help address that collection gap by making reuse more accessible. Clothing and other goods that might otherwise enter the waste stream can instead be collected, sorted, resold, recycled, or distributed to people in need. This aligns with the EPA’s waste-management hierarchy, which prioritizes source reduction and reuse above recycling, energy recovery, and disposal.

However, the value of a donation-bin network depends on how reliably that network can be operated. A full bin that can no longer accept donations represents missed collection opportunities. An overflowing or damaged bin can create an unsightly property condition and undermine community trust. Sending a vehicle to check a bin that is only partially full, meanwhile, consumes staff time, fuel, and vehicle capacity that could be used elsewhere.

That is where remote monitoring can make a measurable operational difference.

 

Fill: Know Which Donation Bins Actually Need Service Fill-level monitoring gives donation centers a live view of capacity across distributed collection points. Rather than treating every location the same, staff can prioritize the bins that are approaching their configured threshold. This can help an organization: Prevent overflow and the placement of donations outside a full container Reduce unnecessary inspections and collections Prioritize high-volume locations during seasonal donation surges Build routes around actual need instead of assumptions Identify underperforming or unusually active collection sites Compare donation patterns by location, day, or time period Make better decisions about bin placement and collection frequency

 

Fall: Respond When a Bin Tips or Its Position Changes Donation bins are frequently placed outdoors in parking lots and other publicly accessible areas. That makes them vulnerable to severe weather, accidental impact, vandalism, unauthorized movement, or improper handling. A fall or tipping alert can give operations teams an early warning that a container may no longer be upright. Instead of waiting for a donor, property manager, or passerby to report the problem, the organization can investigate promptly. Faster awareness can help: Protect donated goods from exposure to rain, dirt, or contamination Reduce obstructions and other hazards around the collection site Limit damage to the bin and its mounting hardware Address vandalism or unauthorized relocation sooner Maintain a cleaner, more professional appearance for donors and host properties

 

Fire: Add an Early Warning for Abnormal Heat Conditions Donation bins may contain textiles, paper, cardboard, and other combustible materials. They may also receive prohibited or inappropriate items despite posted instructions. An unexpected temperature increase can therefore be an important condition to investigate quickly. Our sensors can detect potential fire conditions and transmit an alert through the connected monitoring system. This can give designated personnel an opportunity to assess the situation and initiate the organization’s response procedures sooner. Fire monitoring should be considered an additional layer of operational awareness—not a replacement for approved fire-detection equipment, emergency services, site-specific safety procedures, or applicable fire codes.

 

The Technology Behind the Project: Dingtek DF703 For this donation-center project, Embedded Works is using the Dingtek DF703-US915 LoRaWAN Smart Bin Sensor. The DF703 uses ultrasonic distance sensing to determine the level of material inside a container, with a maximum detection distance of up to four meters. It can also report fall and potential fire conditions. The device communicates over LoRaWAN, a low-power wide-area networking technology designed for small amounts of sensor data transmitted over long distances. Sensor readings travel through a compatible LoRaWAN gateway to a network and application platform where users can view status information, configure alerts, and use the data to support collection planning. Key characteristics include: Remote full, fall, and fire status detection Ultrasonic level sensing with up to a four-meter detection range LoRaWAN connectivity for low-power remote communication More than eight years of projected battery life at a four-hour reporting interval Installation options for covered and uncovered containers A compact 4.53 × 4.53 × 1.57-inch form factor An operating temperature range of –4°F to 158°F Support for collection assignments, route planning, and performance analysis through application software

From Sensor to Complete Monitoring Solution

A successful IoT deployment requires more than selecting a sensor. The complete solution may include mounting, connectivity, LoRaWAN gateways or network coverage, device provisioning, alert rules, dashboards, data integration, and an ongoing maintenance plan.

Embedded Works helps organizations evaluate these moving parts as a complete system. We can work with a team to understand:

• The dimensions, shape, and construction material of the container
• Whether the application is indoors, outdoors, or exposed to harsh conditions
• The material being measured and its expected fill behavior
• The number and geographic distribution of monitoring locations
• Existing LoRaWAN coverage or gateway requirements
• Desired reporting intervals and battery-life targets
• Who should receive alerts and how quickly they need to respond
• Whether sensor data needs to connect with an existing dispatch, asset-management, or business platform

The DF703 is a strong fit for this particular donation-bin project, but it is not the only option. Different container sizes, materials, contents, environments, or network conditions may call for another sensor technology or form factor.

 

Beyond Donation Bins: Monitor Almost Anything in a Container

The same basic concept can support many other industries. If an organization needs to know how much material is inside a container—or whether the container’s condition has changed—there may be a practical IoT solution.

Potential applications include:

• Waste and recycling containers
• Used cooking-oil tanks
• Agricultural feed and grain bins
• Industrial material hoppers
• Parts and component totes
• Laundry, linen, or uniform collection containers
• Medical or laboratory supply bins
• Retail inventory containers
• Construction-material bins
• Food-service ingredient storage
• Document-destruction consoles
• Liquid tanks and intermediate bulk containers

Depending on the application, monitoring can also go beyond fill level to include temperature, humidity, weight, pressure, leakage, door status, movement, vibration, location, or other conditions.

That flexibility is important because the best solution begins with the operational question—not with a predetermined device.

 

Gain Visibility Into Any Remote Container

For donation centers, a bin is more than a metal container. It is a community collection point, a source of reusable goods, an operational asset, and a physical extension of the organization’s mission.

Remote monitoring helps that asset communicate.

By knowing when bins are approaching capacity, when one may have fallen, and when abnormal heat may require attention, nonprofit teams can respond more strategically. They can reduce uncertainty, protect donations, improve the donor experience, and make better use of limited operational resources.

Embedded Works is proud to help 501(c)(3) organizations bring this visibility to their donation-bin networks—and the same approach can be adapted to many other container-monitoring challenges.
