Description

Features

High measurement accuracy and wide range: Humidity range of 5 to 95% RH with a ±5% and also a temperature range of -20 to 60℃ with a ±2%.
Save the I/O resources of the control board: single-bus digital signal output through the built-in ADC
High Stability and Low Cost
Long transmission distance and excellent long-term stability

Grove – Temperature & Humidity Sensor using the upgrade version of DHT11, compere to old version of DHT11, the new version of DHT11 is using type of Capacitive sensor, and The measurement range of temperature and humidity is wider than that of the old version, The temperature resolution is higher. 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. The single-bus digital signal is output through the built-in ADC, which saves the I/O resources of the control board.

Comparison between DHT11 and DHT22

There is another famous DHT sensor on 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:

ITEM	Grove – DHT11	Grove – DHT20	Grove – DHT22
