Can't figure out how to code Multiple SHT10 temp/humid sensors

[cuparguy]

I'm trying to add two SHT10 sensors to a much larger project but cannot figure out how to read from 2 sensors independently. I'm using the sensirion library found at Sensirion Github .

I'm fairly new to this and every attempt to change this code for 2 sensors does not work. Any help would be appreciated.

This is the code:

#include <Sensirion.h>

const uint8_t dataPin  =  5;
const uint8_t clockPin =  6;

float temperature;
float humidity;
float dewpoint;

Sensirion tempSensor = Sensirion(dataPin, clockPin);

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

void loop()
{
  tempSensor.measure(&temperature, &humidity, &dewpoint);

  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.print(" C, Humidity: ");
  Serial.print(humidity);
  Serial.print(" %, Dewpoint: ");
  Serial.print(dewpoint);
  Serial.println(" C");
  
  delay(5000);  
}

I looked on your schematic and could not find the second data pin. With both connected as the software indicates you will get garbage.

Does it work for one sensor?

Schematic?

Where do you have the second sensor attached?

Your code looks almost exactly like https://github.com/spease/Sensirion/blob/master/examples/SimpleSensirion/SimpleSensirion.pde

I think the main change you need is near this line:

@cuparguy

Sensirion tempSensor = Sensirion(dataPin, clockPin);

...you need to instantiate another sensor with a different name on different pins with a line like this completely untested line:

Sensirion tempSensor2 = Sensirion(dataPin2, clockPin2);

What have you tried? And how has it failed?

Yes it does

@DaveX

Schematic?

@DaveX

Where do you have the second sensor attached?

Pins 6 and 7

@DaveX

Your code looks almost exactly like Sensirion/SimpleSensirion.pde at master · spease/Sensirion · GitHub

It is. I'm trying to get the simple code working with 2 sensors.
My problem is

@cuparguy

tempSensor.measure(&temperature, &humidity, &dewpoint);

  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.print(" C, Humidity: ");
  Serial.print(humidity);
  Serial.print(" %, Dewpoint: ");
  Serial.print(dewpoint);
  Serial.println(" C");

How do i distinguish the 2 sensors from each other?

See post #3.

I will give try in the AM. Thank You

[cuparguy]

Completely forgot to update this but thank you.

@DaveX

Sensirion tempSensor2 = Sensirion(dataPin2, clockPin2);

I did not notice the 2 after each at first. It was easy as that. I'm learning a lot.
