Help with esp8266 sketch please: SHT21 temp/humid sensor
Posted: Fri Jul 17, 2015 1:55 pmHello all, can someone please help with my first esp8266 sketch? OK... second sketch, I got "blink" working!
Here is my sketch:
And here is the output:
The humidity value is clearly nonsense. The after the "Temperature(C):" appears, there is a pause of around 1s before the rest of that error message appears.
Thanks,
Paul
Here is my sketch:
Code: Select all
/****************************************************************
* ReadSHT2x
* An example sketch that reads the sensor and prints the
* relative humidity to the PC's serial port

* Tested with:
* - SHT21-Breakout Humidity sensor from Modern Device
* - SHT2x-Breakout Humidity sensor from MisensO Electronics
***************************************************************/
#include <Wire.h>
#include <SHT2x.h>
void setup()
{
Serial.begin(115200);
delay(5000);
Serial.println("Starting Wire...");
Wire.begin(2, 0);
}
void loop()
{
Serial.print("Humidity(%RH): ");
Serial.print(SHT2x.GetHumidity());
Serial.print(" Temperature(C): ");
Serial.println(SHT2x.GetTemperature());
delay(1000);
}
And here is the output:
Code: Select all

The humidity value is clearly nonsense. The after the "Temperature(C):" appears, there is a pause of around 1s before the rest of that error message appears.
