Mioty RF Transceiver Module

Wireless data transmission systems are being increasingly deployed in industrial and home automation applications. These robust systems are used to transmit sensor data and control information across network infrastructures. In the age of the Internet of Things (IoT), people and things will be intelligently connected to one another, leading to innovations in business and Industry 4.0.

Mioty can be deployed for a wide range of applications. The technology is suitable for monitoring large technical systems or difficult-to-access areas and can serve as the underlying transmission infrastructure for applications such as switching statuses, machine-to machine communication, smart meters and other systems. Even sports and security applications require data transmission involving numerous sensors.

WD-QLHM Module

WD-QLHM is module used for the industrial standard Mioty, and supports the 868 / 915 MHz frequency bands; they have highly integrated antennas and MCU suitable for IoT LPWAN network sensor applications. The WD-QLHM module design includes DIO / ADC / UART / SPI / I2C pins for basic applications.
