Design of wireless monitoring system for pump based on STM32 and nRF905

In order to solve problems of complex wiring, high cost and scattered power equipment of traditional pump control system, a wireless pump monitoring system was proposed which was based on STM32 controller and nRF905 wireless radio frequency transmission module. In the system, parameters of pump water supply system are measured by slave station including water pressure and liquid level, and transmitted through one-to-many wireless communication network formed by nRF905. STM32F103 is used for data processing and communication between master station and PC. The test result shows that the system has high sampling precision, reliable data transmission and stable communication.
