Abstract
Aiming at constrains of limited energy and low cost of wireless sensor networks.A wireless sensor networks node localization by sound based on STM32 is proposed.It includes
a microcontroller
a nRF24L01 RF transceiver
a sound sensor
a loudhailer and so on.The node is located by RF and Audio signal.Test result shows that node is measured within 30 meters with error less than 5 %.It has a good application prospect.
