Experimental technique carries out as follows:
1, point-to-point radio communication experiment
Adopt the sequential control of spi bus communication protocol, NRF24L01 realizes the point-to-point communication of radio node.
2, wireless LED lamp flicker experiment
Use the configuration of NRF24LE1 MCU IO mouth.NRF24LE1 is minimum, monolithic super low-power consumption 2.4GHz wireless system chip that integrated level is the highest in the world.
3, wireless humiture collection experiment
Adopt DHT11 unibus Data Control agreement, the DHT11 digital hygro sensor is a humiture compound sensor of calibrating digital signal output that contains.The digital module acquisition technique of its application specific and temperature and humidity sensing technology guarantee that product has the long-time stability of high reliability and brilliance.
The utility model is finished simple Internet of Things with the single chip computer experiment case and is tested, and chip is for opening frequency range, exempting from licence use, integrated level height, and is easy to use, can finish the information of humiture transmission on several collection points, information reception under the wireless environment; Control experiments such as LED lamp flicker under the wireless environment, finish the information transmission under the wireless environment preferably.
