Grove - Temperature&Humidity Sensor (HDC1000)

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.

Note

1 Please plug the USB cable gently, otherwise you may damage the port. Please use the USB cable with 4 wires inside, the 2 wires cable can't transfer data. If you are not sure about the wire you have, you can click here to buy

2 Each Grove module comes with a Grove cable when you buy. In case you lose the Grove cable, you can click here to buy

Hardwave

  • Step 1. Connect Grove - Temperature&Humidity Sensor(HDC1000) to port I2C of Grove-Base Shield.

  • Step 2. Plug Grove - Base Shield into Seeeduino.

  • Step 3. Connect Seeeduino to PC via a USB cable.

Note

If we don't have Grove Base Shield, We also can directly connect Grove - Temperature&Humidity Sensor(HDC1000) to Seeeduino as below.

5V Red
GND Black
SDA White
SCL Yellow

Software

  • Step 1. Download the Seeed DHT library from Github.

  • Step 2. Refer to How to install library to install library for Arduino.

  • Step 3. Restart the Arduino IDE. Open a new sketch, and copy the following code into the new sketch.

#include <Wire.h>
#include <HDC1000.h>

HDC1000 mySensor;
//HDC1000 mySensor(0x41, 2) <-- DRDYn enabled and connected to Arduino pin 2 (allows for faster measurements).

void setup(){
    Serial.begin(9600);
    mySensor.begin();
}

void loop(){
    Serial.print("Temperature: ");
    Serial.print(mySensor.getTemp()); 
    Serial.print("C, Humidity: ");     
    Serial.print(mySensor.getHumi());
    Serial.println("%");
    delay(1000);
}

  • Step 4. Upload the demo. If you do not know how to upload the code, please check How to upload code.

  • Step 5. Open the Serial Monitor of Arduino IDE by click Tool-> Serial Monitor. Or tap the Ctrl+Shift+M key at the same time. Set the baud rate to 9600. If every thing goes well, you will get the results.

The result should be like:

Tip

In this wiki we use the path ~/GrovePi/ instead of /home/pi/Desktop/GrovePi, you need to make sure Step 2 and Step 3 use the same path.

Note

We firmly suggest you to update the firmware, or for some sensors you may get errors.

  • Step 3. Git clone the Github repository.
cd ~
git clone https://github.com/DexterInd/GrovePi.git
  • Step 4. Excute below commands to get the value.
cd ~/GrovePi/Software/Python/grove_i2c_temp_hum_hdc1000
sudo python grove_hdc_1000_example.py

The result should be like:


pi@raspberrypi:~/GrovePi/Software/Python/grove_i2c_temp_hum_hdc1000$ sudo python grove_hdc_1000_example.py
