用户MCU发送一次开始信号后,DHT11从低功耗模式转换到高速模式,等待主机开始信号结束后,DHT11发送响应信号,送出40bit的数据,并触发一次信号采集,用户可选择读取部分数据.从模式下,DHT11接收到开始信号触发一次温湿度采集,如果没有接收到主机发送开始信号,DHT11不会主动进行温湿度采集.采集数据后转换到低速模式。(Send a signal to the user MCU, DHT11 conversion from low power mode to high mode, waiting for a host computer after the start signal, the DHT11 transmits a response signal from the 40bit data, and trigger a signal acquisition, the user can choose to read the data. From the model, the DHT11 receives the start signal to trigger a temperature and humidity if the acquisition, not receiving host sends a signal to start, DHT11 will not take the initiative to the temperature and humidity data acquisition. After conversion to low speed mode.)
