Introducing AHT20 I2C Temperature and Humidity Sensor- Industrial Grade

Let’s also take a look at the Speed of Seeed! How fast Seeed can be?

At Seeed, we provide a lot of temperature and humidity sensors based on different chips such as DHT11, DHT22, and BME280.

In the blog 9 Types of Temperature Sensors You Should Know, we introduced:

  • DHT11
  • DHT22/am2302
  • BMP280
  • BME280
  • DS18B20
  • AF5485
  • AM2311A
  • AHT20 (new release)

Today we bring you the brand new chip called AHT20, an industrial-grade and high-accuracy temperature and humidity sensor with the I2C interface.

Update: Release of Grove – AHT20 I2C Industrial Grade Temperature and Humidity Sensor

Grove AHT20 Temperature and Humidity sensor is based on AHT20, a new generation of temperature and humidity sensor embedded with a dual-row flat and no-lead SMD package, suitable for the reflow soldering. AHT20 is equipped with a newly designed ASIC chip: an improved MEMS semiconductor capacitive humidity sensor, and a standard on-chip temperature sensor. The output is the I2C protocol with the Grove interface.

What is AHT20?

AHT20

AHT20 is a new generation of temperature and humidity sensor:

  • Embedded a dual-row flat and no-lead SMD package, suitable for the reflow soldering.
  • With a bottom surface of 3 x 3mm and a height of 1.0mm.
  • Outputs digital signal in the standard I²C format.

The AHT20 is equipped with a newly designed ASIC chip: an improved MEMS semiconductor capacitive humidity sensor, and a standard on-chip temperature sensor.

The performance of AHT20 has been greatly improved compared with the previous generation of humidity and temperature sensors. The performance of the new-generation temperature and humidity sensor is more stable in harsh environments.

Features:

• Digital output, I2C interface
• Excellent long-term stability
• SMD package suitable for reflow soldering
• Quick response and strong anti-interference ability

Specification:

  • Operating Voltage: DC:2.0-5.5V
  • Measuring Range (humidity) 0 ~ 100% RH
  • Temperature Range: -40 ~ + 85 ℃
  • Humidity Accuracy: ± 2% RH (25 ℃)
  • Temperature Accuracy ± 0.3 ℃
  • Resolution: Temperature: 0.01 ℃, Humidity: 0.024% RH
  • Output Signal: I²C

We are going to release new Grove temperature and humidity sensors soon in a preview below. We hope our new product will help your environmental projects! Let us know your thoughts, we will carefully listen to and take action!
