With the shift to IoT at manufacturing sites, there is a growing need for wireless sensing of equipment dispersed throughout plants and factories. In many cases, continuous measurement is not required for equipment condition monitoring and maintenance.
PiLink offers 920 MHz band LPWA for the domestic market, and 860 MHz band and 2.4 GHz band (ZigBee) for the overseas market, depending on the radio wave certification status of each country. LPWA has been difficult to transmit large amounts of data due to its low speed, but our unique modulation method and retransmission/playback method can transmit approximately 20,000 sensor data points in approximately 5 seconds (transmission distance of 20-30 m). (transmission distance: 20 to 30 m). In addition, the transmission data and timing can be changed through custom development according to customer needs. For example, if you want to transmit only the judgment score by FFT or other judgment scoring on the child unit side, you can choose the LoRa method, which can transmit data from 500 m to 1 km despite its low transmission speed.
