Design of wireless detection module of device temperature in coal mine
Huang Mengtao, Yiming Yan · 2012
A wireless detection module of device temperature in coal mine based on the microcomputer MSP430 and the transceiver nRF905 was designed, the hardware structure of a node in wireless sensor networks, signal transmission and the processes of frequency-hopping spread spectrum(FHSS) were given. This module uses nRF905 to realize FHSS mechanism, delivers the device temperature from nodes to sink nodes and then to surface monitoring computer, while operation status of mining equipment can be safely monitored. The module has a good anti-jamming capability.
