Grove - Temperature & Humidity Sensor is a high quality, low-cost digital temperature and humidity sensor based on the DHT11 module.

Grove - Temperature & Humidity Sensor is a high quality, low-cost digital temperature and humidity sensor based on the new DHT11 module.
 
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. E.g. 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 is wider, temperature resolution is higher. You can check the following figure for more detail.

There is another famous DHT sensor in our website--Grove DHT22. Compared with DHT22, the DHT11 sensor is more cost-effective, but the measurement range and accuracy are lower. The Grove DHT11 can be a low-cost alternative to the Grove DHT22 when accuracy requirements are not as high. Please refer to the following table for the difference between those two:
