Online dust monitoring system

With the vigorous development of national real estate construction and the increase in construction projects, the problem of dust pollution caused by construction has become increasingly serious. In order to effectively and quickly monitor the dust conditions at the construction site, we use a hardware platform to collect dust PM2 at the construction site. 5/pm10 content information, the dot matrix screen displays the content information on site, and transmits the pm particulate matter (PM10/PM2.5) content information to the China Mobile OneNet platform through the GPRS network, and the dust regulatory authorities can view the dust content information through the platform. And it can be viewed through the mobile phone, which greatly facilitates the monitoring and control of dust pollution.

STEP400: 4-axis stepper motor driver for creative encoders (schematic, PCB, source code, etc.)

STEP400 is a stepper motor driver board that can control up to 4 axes. STEP400 elegantly combines all necessary functions, from communication to motor control, into a simple and complete package. STEP400 uses Open Sound Control (OSC) based on standard Ethernet rather than specialized industrial protocols to achieve ease of use while ensuring it is reliable enough for use in art, design or any other creative application. STEP400 can be easily controlled through creative coding environments such as openFrameworks, Processing, Max, Unity or Touch Designer. STEP400 is Arduino compatible, so you can drive the motors with your own code too.
