本人学生一枚，做过的大实验不多，现将我上学期做过的有关总线型智能温室大棚设计中五个传感器的代码奉上。我们涉及的传感器有空气温湿度传感器（DHT22）、土壤湿度传感器（FC-28）、土壤温度传感器（ds18b20）、光照传感器（bh1750FVI）、一氧化碳传感器（MQ7）,其中土壤湿度传感器和一氧化碳传感器为模拟输出，所以用到了A/D转换，用的A/D转换器为ADS1256。-I am a student, done a lot of experiments, I have done last semester on the bus intelligent greenhouse design of the five sensors on the code offer. The soil moisture sensors and carbon monoxide sensors are simulated in the soil temperature and humidity sensors (DH18), soil moisture sensors (FC18), soil temperature sensors (CB1820), light sensors (bh1750FVI) and carbon monoxide sensors (MQ7) Output, so the use of A/D conversion, with the A/D converter for the ADS1256.
