STMicroelectronics STEVAL-WL33WMKCB
Water metering based on LCSC using STM32WL33
The water metering STEVAL-WL33WMKCB board is composed of the MB2029 mother board, where the STM32WL33CC board is mounted, the STEVAL-WL33LCSC LC board for water meter flow measurement, and the STEVAL-WL33LCD LCD board. It can show the corresponding revolutions with STEVAL-WL33WMK1 over LCD on STEVAL-WL33LCD. The MCU RF board MB2029 houses the STM32WL33CC microcontroller, which is an ultralow power device with an embedded sub-GHz transceiver for wireless communication. It shows the corresponding revolutions with the STEVAL-WL33WMK1 over LCD on STEVAL-WL33LCD. The STEVAL-WL33WMK1 features two user LEDs that indicate the wheel's rotation in clockwise or anticlockwise directions. The board can improve water supply management, distribution efficiency, customer service, and billing processes by supporting advanced features such as multitariff billing.
