DHT11 and DHT22 Sensor Using with Arduino - YouTube

I have code which read temperature and humidity using DHT11 sensor. I uploaded following code using Arduino via USB serial, I can read values of temp, humidity. Values are being read as long as Arduino is connected to same laptop via USB. TEMPERATURE AND HUMIDITY are being read as 0 when I power on Arduino using DC12v, 700MA adapter.

Read DHT11/22 Temperature Humidity Sensor from Raspberry

Read DHT11/22 Temperature Humidity Sensor from Raspberry Pi. However, using pure Python to read DHT11/22 sensor might not get ideal result, since the CPU has bigger chance to be assigned with other tasks during the reading, and cause very high chance to fail, which make it almost not usable. or using an Arduino to read the DHT sensor
