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.
