DesignSpark Project #2 'HygieneDispenser'
This MakerVideo describes how to build a simple HygieneDispenser using only a few components. The heart of the application is a lococube® mini-PLC, toggled by a photoelectic reflective sensor driving a 12V gear pump. The open source project also provides the mini-PLC application for free download. The program can easily be changed to customers requirements.
Once the sensor detects an object getting closer, one digital of the mini-PLC will be toggled high. Now the application runs time-related delays and lock times to directly drive a gear pump connected to the mini-PLCs output. The gear pump pressurizes the desinfectant to be applied to your hands by a fine nozzle.
DesignSpark Project #1 'PeopleCounter'
The project, called ‘People Counter’, can be constructed in less than an hour and records the amount of people entering and leaving a room, indicating when it is safe to enable more people to enter while still keeping the recommended distance from others. This is especially effective in retail environments where safe social distancing can be challenging to control.

Two photoelectric proximity sensors or light barriers, identify the direction of movement, while a miniature PLC calculates the amount of people in and out of the store in real-time. A password-protected CAN touch screen is employed to pre-set the maximum people limit and also works as a ‘traffic light’ system, illuminating green when access is allowed and red when access is refused. There is also an audio alert. The miniature PLC processes the data and controls the display.
