Wireless Display Kit

Description

This display unit can receive and display transmitted data from any JemRF radio modules/sensors. The display features an 8-digit layout with decimal places between digits. It can also be easily converted into a professional display case. Custom messages can be sent from a PC, Raspberry Pi, or Arduino using the provided RF Flex module or an IoT Gateway for Raspberry Pi. No microprocessor is needed to display data directly from JemRF sensors. For example, wireless temperature sensor readings can be automatically received and displayed without using a microprocessor like a PC, Raspberry Pi, or Arduino.
