In order to solve the ecological environment rapeseed field data collection process data transfer was slow,storage capacity is small,the laying of sensor lines and adjust the difficult issues,has designed a wireless data collection devices,the device integrates a microcontroller CC1110 with a wireless module,SHT71 temperature and humidity sensors,TSL2561 illumination sensor,SWR soil moisture sensors. Data receiving module with PC computers using the MAX3232 serial communication.and ultimately achieving the data multi-point timing measurements,the node battery-powered,a large number of data transmission and preservation purposes.
