Grove - temperature & humidity sensor
Description
The Grove DHT20 sensor is a high-quality digital temperature & humidity sensor and an improved version of the DHT11. The DHT20 features a brand-new ASIC chip, an improved MEMS semiconductor capacitive humidity module, and a standard on-chip temperature element. Due to its miniaturization and design changes, the DHT20 is more robust in harsher conditions! The DHT20 is also more versatile with its I2C signal, which supports multiple masters!
With its extended and more precise measurement range, the DHT20 is suitable for various IoT applications, especially applications such as plant cultivation and quality control.

What is Grove?
Grove makes connecting and experimenting easier and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed, covering a wide range of applications and meeting a variety of requirements. Not only the hardware but also the software is open source. For Grove users (especially beginners), instructional PDF documents and a wiki are provided.
We offer various Grove Shields to enable connections to the Grove system with various microcontrollers.
