Hi Guys,
I am pretty new to Arduino and I2C stuff in general.
Could someone give me a hint on how to use two TH02 sensors simultaneously?
I have one sitting on 0x40 and 0x68, but simply do not manage to address them indvidually.

Thanks a lot!!

I am having issues running the demo on the Intel Galileo board. The issue I am getting:
TH02_dev.cpp:37:20: error: no matching function for call to 'TwoWire::TwoWire()'

This is the line where error is coming from:
TH02_dev::TH02_dev()
{

}

Should TH02_dev() be empty?

Is it possible to use this module with Raspberry Pi Base Hats?

Hi,

I have an issue with this Sketch:

Arduino: 1.8.19 (Mac OS X), Board: "Arduino Uno WiFi Rev2, ATMEGA328"

'TH02' was not declared in this scope....

I'm quite new to coding so I don't know what else you need....

here is the full sketch...

#include <TH02_dev.h>
#include "Arduino.h"
#include "Wire.h"
void setup()
{
Serial.begin(9600); // start serial for output
Serial.println("TH02_dev demo by seeed studio\n");
/* Power up,delay 150ms,until voltage is stable /
delay(150);
/ Reset HP20x_dev /
TH02.begin();
delay(100);
/ Determine TH02_dev is available or not */
Serial.println("TH02_dev is available.\n");
}
void loop() {

float temper = TH02.ReadTemperature();
Serial.println("Temperature: ");
Serial.print(temper);
Serial.println("C\r\n");
float humidity = TH02.ReadHumidity();
Serial.println("Humidity: ");
Serial.print(humidity);
Serial.println("%\r\n");
delay(1000);

}

Hello,

first of all I'm new in coding and in IOT stuff, sorry if ii do'nt use the right synthaxe.

I have an issue with this Sketch:

Arduino : 2.1.0 ( windows 10), Board : " Arduino MKR WIFI 1010"

here is the full sketch ( i use the exemple TH02_demo)

#include <TH02_dev.h>
#include "Arduino.h"
#include "Wire.h"
#include "THSensor_base.h"

#define ShowSerial Serial
#ifdef AVR
#include <SoftwareSerial.h>
SoftwareSerial SSerial(2, 3); // RX, TX
#define COMSerial Serial
#define ShowSerial Serial
TH02_dev TH02;
#endif

#ifdef ARDUINO_SAMD_VARIANT_COMPLIANCE
#define COMSerial Serial1
#define ShowSerial SerialUSB
TH02_dev TH02;
#endif

#ifdef ARDUINO_ARCH_STM32F4
#define COMSerial Serial
#define ShowSerial SerialUSB
TH02_dev TH02;
#endif

void setup() {
ShowSerial.begin(9600); // start serial for output

ShowSerial.println("****TH02_dev demo by seeed studio****\n");
/* Power up,delay 150ms,until voltage is stable */
delay(150);
/* Reset HP20x_dev */
TH02.begin();
delay(100);

/* Determine TH02_dev is available or not */
ShowSerial.println("TH02_dev is available.\n");

}

void loop() {
float temper = TH02.ReadTemperature();
ShowSerial.print("Temperature: ");
ShowSerial.print(temper);
ShowSerial.println("C\r\n");
//Serial.print("%\t");

float humidity = TH02.ReadHumidity();
ShowSerial.print("Humidity: ");
ShowSerial.print(humidity);
ShowSerial.println("%\r\n");
delay(1000);

}

my issue is : i always have the sames results, humidity = 24% ans Température = 50°C

and i still have there result if i unplug my sensor :/

I have try other code the results are the same.

For plug my sensor i have follow the documentation and connect

black --> GND
RED--> 5V
white--> SDA
YEllow --> SCL

Thank in advance,

Hello,

@jeferrb and I, we are trying to use the TH02 on Intel Edison, but in environments with A/C (< +22°C ~ +24°C) this code below does not work (program get stuck) after few minutes:

#include <Wire.h>
#include <TH02_dev.h>
#include "rgb_lcd.h"

rgb_lcd lcd;

int counter = 0;

void setup() {
	lcd.begin(16, 2);
}

void loop() {
	float temperature = TH02.ReadTemperature();
	lcd.clear();
	lcd.print("loop() [");
	lcd.print(++counter);
	lcd.print("]");
	lcd.setCursor(0, 1);
	lcd.print(" - Temp: ");
	lcd.print(temperature);
	lcd.print(" C");
}

There is sometime related with this issue below?
