Datacake Dust Control
This is the official datasheet for the Datacake Dust Control Particulate and Fine Dust monitoring device.


The Datacake Dust Control is based on the Datacake Multi Network Sensor Node and is a device for detecting fine dust pollution in industrial environments.

Industry 4.0

The Dust Control has three different communication interfaces and can be integrated into a LoRaWAN network. So use the Dust Control for the setup of use cases for the industry 4.0

Helps you save energy

The Dust Control has an integrated switching output to switch machines via potential-free inputs or relays.
So you can use the Dust Control for the control of filter systems and let them only switch on when there is a real need (i.e. when the air is bad).
This can also be done without a gateway or networking. The switching function is implemented directly on the device.

Complex Automation

With LoRaWAN network, however, several sensors and actuators can be interconnected and complex automations can be set up. Thus, you can control the entire room ventilation.

Principle of Operation

Dust Control is a fine dust measuring device with integrated optical particle counter. It takes a sample from the ambient air via an integrated fan and analyzes it for ultrafine dust contamination.

Sensor Readout

The measurement result is read (sensor readout) from the sensor every five seconds (individually adjustable) by downstream electronics and monitored for changes.


The transmission via LoRaWAN module is realized as follows:
  • If there are major changes compared to the previous sensor readout, the measured value is immediately transmitted via a LoRaWAN radio module.
  • If there are no major changes, the measured value is nevertheless transmitted regularly every five minutes
Both the threshold for immediate transmission and the regular transmission interval can also be set remotely via LoRaWAN downlink.


Digitally Calibrated

The sensor comes with an individual calibration at the factory and requires no further recalibration during its lifetime.


To ensure that the sensor can also be used in harsh environments, such as welding fumes in industry or heavy industrial dusts, the sensor has an automatic cleaning function that takes care of cleaning the sensor unit once a week.

Signaling of Air Pollution

Using an RGB LED on the front of the Dust Control, the current value of air pollution by fine dust is displayed via a color change, which slowly and continuously changes from green (good air) to red (bad air) as the air quality decreases.
  • The limit value for the degree of pollution can be set individually via downlink or Bluetooth.
  • The signaling can also be completely deactivated via downlink, Bluetooth or on the device itself.

Bluetooth Connectivity

The Dust Control has a Bluetooth low energy module, which can be used via a special app for the following functions:
  • Readout of the real-time values
  • Setting the configuration

Standalone Mode

Via the Bluetooth connection and the Dust Control App, the measured values of the device can also be read out directly and without a cloud, since the current measured values are output via the Bluetooth interface.
Please note, however, that some functions will not be available then:
  • No data storage and no historical measured values
  • No exporting of data
  • No Alerting via E-Mail or SMS
  • No calculation of average values
  • No rule engine and therefore no communication between other devices

LoRaWAN Connectivity

The platform of the Dust Control offers a LoRaWAN module, which transmits the measured values via the decentralized LoRa radio network to a central LoRaWAN gateway.
Thus, for example, several sensors can be distributed within a closed indoor area.

High range

An enormous advantage of the LoRaWAN system is the high range of the wireless network. The Dust Control can easily reach a range of several hundred meters within closed buildings.

Requires Gateway

To operate a LoRaWAN network you need a gateway. This is where the cost-effective Datacake LoRaWAN Gateway comes in.
Thanks to the enormous range of a LoRa network, you can place the gateway anywhere and then distribute the sensors accordingly within your company.
You can also operate hundreds of sensors on one gateway and the Dust Control can be operated in conjunction with additional sensors or actuators. The Datacake LoRaWAN Gateway is also compatible with all LoRaWAN devices on the market.
The entire configuration of a Dust Control can be changed remotely via the LoRa network and is then persistently stored on the device.
On the Datacake platform, a simple web interface is available to control the downlinks.
  • Set Dust Control configuration via Downlinks
  • Persistently stored on the device
  • Simple to use Web-Interface for sending Downlinks

Works with any LoRaWAN Server and Gateway

You can also operate the Datacake Dust Control outside of the Datacake ecosystem and of course use LoRaWAN Servers and Gateways from other vendors.
  • Runs with any LNS (TTN, TTI, Loriot, Kerlink Wanesy, ChirpStack, etc.)
  • Payload decoder available
  • Compatible to any 8-Channel LoRaWAN Gateway

Standalone Mode

Using the Bluetooth interface, the sensor can also be operated in standalone mode without LoRaWAN network. It then displays the current level of air pollution via RGB LED on the front panel.

Datacake Platform

The purchase of a Dust Control includes a free license to use the Datacake platform. There are no monthly costs.
This license includes the following features.

Data Storage

The measurement data of your Dust Control is stored in high resolution for the last 7 days.

Data Export

At the push of a button you can export the measurement data as Excel or CSV file directly from the platform.

Open API

Datacake offers an open API for the readout of measurement data or the transfer to external systems.


The Datacake platform includes a dashboard specially designed for Dust Control that displays all important measurements and parameters.

Easy to understand

Instead of displaying complicated measurement results and values, the Dust Control displays the general air quality as a single value.
With just one quick view you can see the current level of air pollution with the help of a stop light (parallel to the stop light that you see on the sensor itself) that shows you the status of the air quality. A "green" indicates that everything is OK and a "red" if it is not.
  • Degree of air pollution in percent
  • Warning light for exceeding the limit values
  • Individually definable limit values

Global Dashboards

In your Datacake Workspace you can create global dashboards that can display readings from multiple sensors.
  • Distribute multiple Dust Control across your organization and view the status on a central dashboard.
  • Combine your Dust Control sensors with other Datacake-enabled sensors and view them on a common dashboard.
With the click of a button you can create a link to your global dashboard and make it publicly available. Anyone who has this link will have access to a public version of the dashboard and will not need a Datacake account.
  • Create shareable Links to your Dashboards
  • Send these to Customers or any other person
  • No need for Sign-Up on Datacake / Datacake Account

Advanced Analysis

The combination of Datacake platform and Dust Control enables advanced analysis of measurement data.
  • Number of limit-overruns per day / week / month
  • Average values for 4, 8 or 24 hours
  • Degree of air pollution in percent

Always Included

Since use of the Datacake platform is included in the purchase price free of charge, these functions are of course always available to you.

Rule Engine

The rule engine allows you to set limits and determine actions that will be executed when these limits are exceeded or not reached. The following actions are possible.


Let the Rule Engine inform you by e-mail or SMS if the defined limit for the degree of air pollution has been exceeded and the condition has therefore changed to "bad".
  • Send e-mail or SMS to any recipient (whether Member of your Datacake Workspace or external).
  • Specify text and subject and use placeholders to specify measured values in the text.


Use the degree of air pollution or other, individual measurement value triggers for the control of machines or actuators. Control commands can be sent to devices via the Datacake Rule Engine.
This allows you to implement even complex automation processes by interconnecting several sensors and actuators. An assignment is not only possible 1:1, but also 1:n, n:1 or n:n.
  • Use the Dust Control for the control of filter systems and help your customers to save energy.
  • Switch outputs of different LoRaWAN hardware modules via downlink.
  • Call any LoRaWAN Downlink.
  • Create complex automation between multiple sensors and actuators.


The Rule Engine also has an editor for sending webhooks. This is a standard that you can use to control external software services or messenger services, for example.
APIs from other cloud systems can also be accessed. This allows you to integrate home automation systems, for example.
  • Create custom Webhooks that send action to third-party software or messenger services.
  • Add your own Header and Payload Data using an intuitive editor.


With the tools for collaboration you can invite your own employees to your workspace and assign the rights that the member should have from now on during the invitation.


Create your own areas on the platform, which you can use for your projects or customers. Devices and members can be moved freely between these Spaces, but can also be present in several Spaces at the same time.
Even in the basic license the following things are always included:
  • Unlimited number of clients
  • Unlimited members
  • Upload your own logo
