TH02 does not work on Intel Edison

[gustavotemple]

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? https://github.com/intel-iot-devkit/upm/issues/351

Hi, sorry for the late reply, do you still have this issue now? If so, what kind of "not work" do you mean? program get stuck? temperature not accurate?

Hello @KillingJacky, Yes, the program get stuck

OK, program getting stuck means the I2C reading fails all the time, and the library falls into a while true loop. Typically this may happen when the sensor is placed to work under critical environment. From your description, very cold enviroments (< 24°C), 24°C can't be said very cold, can I suppose it to be -24°C? If so, from the specification of this sensor, it only works under:

Humidity: 0% - 80% RH 
Temperature: 0 ~ 70 °C

Hello @KillingJacky,

Sorry, I fixed the description, I live in Brazil, so +22°C is very cold for us.
