Description 

 

DHT11 is the most common temperature and humidity module for Arduino and Raspberry Pi. It is widely favored by hardware enthusiasts for its many advantages such as low power consumption and excellent long-term stability. Relatively high measurement accuracy can be obtained at a very low cost. The single-bus digital signal is output through the built-in ADC, which saves the I/O resources of the control board.

 

On top of that, Grove - Temperature & Humidity Sensor uses the upgraded version of DHT11. The new version of the DHT11 module replaces resistive humidity components with capacitive humidity components. The temperature and humidity measurement range are wider. The temperature resolution is higher. You can check the following figure for more detail.
