| Abstract: | In this paper,it is introduced that a portable system used to collect temperature,press and humidity data and based on radio transmission.Its hardcore is the two-way data transmission channel constituted of the radio transceiver single-chip nRF403 and coding and decoding chip PT2262/2272, which makes sending data and receiving instruction being time-sharing.It is controlled real-time by single chip converting state to send or receive data. |
