5 most asked questions about smart bin sensors

by Alexander Bonde

  1. What are the specifications of a WasteHero fill-level sensor?

The fill-level sensors from WasteHero utilize optical sensing technologies to measure the fill level in bins and containers. Additionally, our fill-level device is attached with a wireless accelerometer that functions as a tilt and vibration sensor to detect when a bin or container is emptied. 

Smart bin sensors also come with a TMP1075 temperature sensor, a battery lifetime detector, magnet sensor combined with a buzzer for the hardware user interface and an internal antenna.

It is possible to attach an external antenna directly to the optical flow sensor to ensure connectivity even in the most remote places. Furthermore, it is possible to receive the fill-level devices with an ultra-compact GPS module embedded (GNSS L68) for tracking the waste bins.

Below you kind find all the specification of the sensor:

  1. Why use optical sensing technology?

At WasteHero, we have developed our fill-level device using optical technology. This means that we use the optical flow measurement, which is applicable for any type of waste.

The ultrasonic technology is widely used in almost all cars with parking sensors. The ultrasonic technology is good at detecting distances between various material types, however, it has a downside since the first 15 - 20 cm cannot be measured by it.

Therefore, WasteHero is utilizing the optical sensor, which has different qualities, making it one of the most accurate fill-level devices on the market. The optical sensor can measure distances between 0 – 400 cm and has the ability to map out the waste in 3D, which allows for an accurate estimate of what various filling patterns can mean in fill-level. This also makes it possible for our device to measure uneven surfaces.

 

  1. What networks do you support?

 

At WasteHero, we have developed a fill-level device, which can be used on all of the most recognized IoT networks, namely: LoRaWAN, Sigfox and NB-IoT (Narrow-Band).

Additionally, the device supports GSM (Global System for Mobile Communications), since this network has the largest coverage across the world.

 

  1. How is the smart bin sensor mounted?

The fill-level device from WasteHero can easily be mounted in both new and existing bins. We provide mounting options for various types of containers to ensure that more waste is being handled in a more efficient way.

The mounting of the fill-level device can be done in a few minutes. The sensor is creating with an easy mounting in mind, which is reflected in the design. In each corner of the fill-level devices is a hole for mounting. 

For plastic containers, it simply requires 4 screws and the sensor is mounted. For metal containers, 4 holes are predrilled using our template and we then provide both the bolts and jam nuts required to mount the sensor.

Additionally, WasteHero has developed a mounting bracket for adjusting the angle, which can be used for special and open containers to ensure an accurate measurement.

  1. How is the data accessed?

WasteHero provides several options for accessing the data based on your requirements.

 

Smart Waste Management Platform

At WasteHero, we have developed a platform for Smart Waste Management, which allows you to easily access the data from fill-level sensors, which is presented in a user-friendly and manageable way. 

The platform is pre-integrated and hosted on a cloud server. Furthermore, the platform comes with multiple beneficial functions such as route-planning, smart analytics, an overview of mounted bins and much more. 

If you wish to test the platform before making an investment, contact a WasteHero specialist and we can provide you with a free demo version to try the various features.

The platform is also easily customized to suit your specific needs and scalable to add other devices for various projects.

 

Software Integration

It is also possible to integrate WasteHero’s Smart Waste Management Platform to an existing platform. The work required for this differs depending on the specifications of an existing platform.

 WasteHero has some incredibly skilled software developers and has also experience with multiple EU projects regarding software integration. If you require a software integration of our platform to an existing platform, we suggest that you schedule a meeting with one of our specialists to discuss specifications and requirements.

 

API Access

The last option currently supported by WasteHero is accessing the data through our API. WasteHero is utilizing an open API, enabling us to simply forward the data from the fill-level devices directly to an existing platform.
