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 capacitance humidity module and a standard on-chip temperature element. Due to miniaturization and modifications, the DHT20 is more robust in harsher conditions! The DHT20 is also more versatile with its I2C signal supporting multiple masters!

With the extended and more precise measurement range, the DHT20 is suitable for various IoT applications, especially for applications such as crop cultivation and quality control.

Features

  • High accuracy:
    • Temperature accuracy: ± 0.5 ℃
    • Humidity accuracy: ± 3% RH (25 ℃)
  • Wide measuring ranges:
    • Measuring range (humidity): 0 ~ 100 % RH
    • Measuring range (temperature): -40 ~ + 80 ℃
  • Better compatibility:
    • Digital output
    • I²C interface
  • Fully calibrated
  • Excellent long-term stability
  • Fast response and noise immunity capability
  • Wide voltage support: 2.5-5.5V DC

 

Applications

  • HVAC (heating, ventilation, air conditioning)
  • Dehumidifiers
  • Test and inspection equipment
  • Equipment
  • Consumer goods
  • Automotive
  • Automatic control
  • Data recorder
  • Weather station
  • Humidity control
  • and other related projects for temperature and humidity measurement and control

What is Grove?

Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. Instructional PDF documents and a wiki are provided for Grove users (especially beginners). 

We offer various Grove Shields to enable connection to the Grove system with various microcontrollers.
