| Abstract: | This paper introduces a kind of wireless temperature measuring and alarm system based on nRF24E1 chip. The system can collect and transfer the data of temperature on real time. When the temperature is higher than the upper limit value, the system will alarm through sending out off sound and light. The 1- Wire bus digital thermometer DS18B20 is used to measure temperature. It can realize the 1- Wire multi- point collection. The system use embedded MCU- 51 kernel of RF transceiver chip nRF24E1 to transfer the data wirelessly. The paper firstly introduces the hardware design and the working principle of correlative chips. At last it gives the software design thought. So the function of wireless temperature measuring and alarm is come true. |
