Abstract:

In view of the drawbacks of the timer switches available on the market,a timer switch based on the STM32 processor is proposed.The device uses the GSM network to the remote control functions.The wireless communication module nRF24L01+ can remote control more than one randomly distributed switch within a certain range.The system has a friendly communication interface providing such functions as time setting,infrared remote control,touch screen control,and power-down protection.

Key words: STM32;TC35;remote control;multi-point distribution;timer switch
