Grove - Temperature&Humidity Sensor (HDC1000)

Introduction

3.3V 5.0V I2C

Grove - Temperature&Humidity Sensor (HDC1000) utilizes a HDC1000 sensor.HDC1000 was designed by Texas Instruments.It is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power.The device measures humidity based on a novel capacitive sensor.The humidity and temperature sensors are factory calibrated.The innovative WLCSP (Wafer Level Chip Scale Package) simplifies board design with the use of an ultra-compact package. The sensing element of the HDC1000 is placed on the bottom part of the device, which makes the HDC1000 more robust against dirt, dust, and other environmental contaminants. The HDC1000 is functional within the full –40°C to +125°C temperature range,and 0-100% RH range.

Get Started

With Arduino

Here is how to use Grove - Temperature&Humidity Sensor (HDC1000) with Seeeduino Lotus.

Hardware Installation

  1. Part lists:

    • Seeeduino Lotus v1.0 or other Microcontroller development board that combination of Seeeduino
    • Grove - Temperature&Humidity Sensor (HDC1000).
  2. Hardware linking is very easy.Grove - Temperature&Humidity Sensor (HDC1000) communicate over I2C. Connecting Grove - Temperature&Humidity Sensor (HDC1000) and Seeeduino Lotus v1.0 by Grove cable, as shown below.

Software Part

  1. To download the demo code in github, click here.
  2. To install Arduino Library, please click here
  3. Open the HDC1000 example sketch
  4. In the Tools -> Board menu, select right board and serial port.
  5. Upload demo code to Seeeduino Lotus v1.0.

We can get the temperature and relative humidity information from the serial terminal

With Launchpad

Material required

Hardware connections

Download code and flash it to Launchpad

  1. Download the demo code.

    Note

    You have to copy the file readTempHumi.ino (in the folder examples) into the same folder as HDC1000.h.

  2. Flash the code into Launchpad.

  3. Open Serial Monitor (Tool->Serial Monitor) to view data detected.

Caution

The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
