Connection with Raspberry Pi

The flashing is terminated immediately on sending a command to the RLY08 and then becomes a power LED

Gravity: DHT11 Temperature & Humidity Sensor For Arduino SF_RFID Antennas and is very easy toDFRobot's latest generation of digital DHT11 Temperature and Humidity sensor is as powerful as it used to be but easier to use. This DHT11 Arduino temperature and humidity sensor has a full range temperature compensation, low power consumption, long term stability and calibrated digital signal. A high performance 8 bit microcontroller is integrated in the sensor with calibration coefficient saved in OTP memory to provide accurate temperature readings.
