Abstract: By applying MSP430 as a micro-controller unit, this paper focuses on the design of sensor nodes for a mine wireless roof separation monitoring system. The main work is to use a wireless wake mode (WOR) to periodically monitor the channel, collect the roof-shift data in real time, and send data to monitoring sub-station by RF communication module. Based on the analysis of low-power MSP430 principle and work mode, this article introduces the low power node design in detail from hardware design, work principle and communication mode, also its low power applications achievement. The wireless sensor nodes are of low power consumption and high reliability, so that maximize the use of limited energy, and have a high practical value in the harsh environment of mining.
