Detailed Description

Blocking RHT03 temperature/humidity reader. Call begin(), then update() before accessing cached readings; the caller controls the sampling interval.

Member Function Documentation

begin()

void RHT03::begin

(

int

dataPin

)

Bind and configure the data GPIO as INPUT_PULLUP.

Parameters

dataPin

Sensor data pin.

update()

int RHT03::update

(

)

Read and validate a sensor frame synchronously.

Returns

1 on success; zero or negative values indicate timing or checksum errors. Only a successful read updates the cached temperature and humidity.
