Reading Digital sensor Via arduino

[Morvy187]

Reading Digital sensor Via arduino in labview [RHT03 high effcient Tempreture and Humidity sensor ] this sensor reads like following ....

If the data transmission is right, check-sum should be:
Check sum=8 bit integral RH data+8 bit decimal RH data+8 bit integral T data+8 bit decimal T data
Example: MCU has received 40 bits data from RHT03 as
0000 0010 1000 1100 0000 0001 0101 1111 1110 1110
16 bits RH data 16 bits T data check sum
Check sum=0000 0010+1000 1100+0000 0001+0101 1111=1110 1110
RH= (0000 0010 1000 1100)/10=65.2%RH
T=(0000 0001 0101 1111)/10=35.1
When highest bit of temperature is 1, it means the temperature is below 0 degree Celsius.
Example: 1000 0000 0110 0101, T= minus 10.1
16 bits T data

you can check the data sheet .......How to read the digital input of this sensor and Display both Tempreture and humidity ...thanks in advance

Hi!

Searching the web I've found a few examples (connections and sketchs) to read from RHT03.

Once you have read the values, you could stream them from arduino board to the PC via the serial interface.

what am asking is how do i do it on labview by using arrays block or I2C block how .....to ready the Sensor

you'll have better luck there with hobbyists who use Arduino and LabVIEW

if you've worked with serial communication, arduino done in this example can help you
