The wireless programmer based on the NRF9E5 chip is proposed, designed and applied. The circuit board doesnt connect to the computer with any cable, and it connects to the computer through the wireless transmission of the NRF9E5. The circuit board can realize to update the program online through the exquisite programmer. The programmer can download the program for 5.97 seconds and it is widely applied to the product development and quantity production area.

The output of pressure sensor is affected by non-objection parameters in its application, its defect is the sensitivity to temperature. The method of the data fusion from the two sensors based on BP network can eliminate the side effect of temperatures and improve the accuracy and reliability for the pressure sensors. This method based on Levenberg-Marquardt algorithm of BP network has not only a simple network structure, but also a quick learning rate, showing a better prospect.
