Resgreen Group International Inc. launched two new wireless pushbutton devices, which can be used in a wide variety of material handling applications in warehouses, manufacturing facilities and more. Pushbuttons allow humans to interface with automation equipment to verify and initiate tasks. Resgreen provides two wireless pushbutton models that feature either an OLED or electronic paper (ePaper) display to relay additional information. Resgreen uses MQTT, a standard messaging protocol for the Internet of Things (IoT), which allows its industrial automation devices to easily connect to other equipment, sensors and control systems in a reliable and scalable manner.

The wireless pushbuttons are designed to integrate easily with BotWay, Resgreen's premier software system, but can also connect with other software systems without any additional wiring or engineering. Because the devices are wireless, they can be placed in any location or on moving objects and do not require a radio. The OLED pushbutton can include up to 32 buttons or inputs and features a small black-and-white display that shows only limited text.

The ePaper device can include up to four buttons and has a larger display that mimics the appearance of ink on paper. It can show grayscale graphics and large QR codes. The pushbutton ePaper device has been used to replace shelf labels in grocery stores, enabling pricing and product information to be updated via a computer versus manually.

It can also display a barcode for use in warehouse picking operations.
