  • Celsius temperature value [℃]

• NG

  • Type: False

### ‘humidity’

• OK

  • Type: float

  • Relative humidity value [%]

• NG

  • Type: False

# Sample

Run sudo pigpiod before running the sample.

## Simple

# -*- coding: utf-8 -*-
import pisht30 as SHT30
import time

obj = SHT30.PiSht30()
try:
    while True:
        value = obj.read()
        if (isinstance(value['temperature'], float)):
            print(round(value['temperature'], 2))
        if (isinstance(value['humidity'], float)):
            print(round(value['humidity'], 2))
        time.sleep(10)
except KeyboardInterrupt:
    pass

## Modify config

‘address’ is HIGH and ‘mode’ is PERIODIC_MPS_1_0_HIGH.

# -*- coding: utf-8 -*-
import pisht30 as SHT30
import time

config = {
    'address' : SHT30.Address.HIGH.value.
    'mode' : SHT30.Mode.PERIODIC_MPS_1_0_HIGH.value
}
obj = SHT30.PiSht30(config)
try:
    while True:
        value = obj.read()
        if (isinstance(value['temperature'], float)):
            print(round(value['temperature'], 2))
        if (isinstance(value['humidity'], float)):
            print(round(value['humidity'], 2))
        time.sleep(10)
except KeyboardInterrupt:
    pass
