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