Detailed Description

template<uint8_t PIN1, uint8_t PIN2>
class MiniR4DHT11< PIN1, PIN2 >

A template class to interface with the DHT11 temperature & humidity sensor.

This class provides methods to read temperature and humidity data from a DHT11 sensor, as well as error handling mechanisms.

Template Parameters

PIN1	Unused in current implementation, can be defined for future expansions.
PIN2	The GPIO pin connected to the DHT11 sensor.

Member Function Documentation

getErrorString()

template<uint8_t PIN1, uint8_t PIN2>

String MiniR4DHT11< PIN1, PIN2 >::getErrorString ( int errorCode )

inline

Converts error codes into human-readable strings.

Parameters

errorCode

Error code to convert.

Returns

String describing the error.

Definition at line 127 of file MiniR4_DHT11.h.

readHumidity()

template<uint8_t PIN1, uint8_t PIN2>

int MiniR4DHT11< PIN1, PIN2 >::readHumidity ( )

inline

Reads and returns the humidity from the DHT11 sensor.

Returns

Humidity percentage, or an error code if the reading fails. Error codes:

• 254: Checksum mismatch
• 253: Timeout

Definition at line 87 of file MiniR4_DHT11.h.

readTemperature()

template<uint8_t PIN1, uint8_t PIN2>

float MiniR4DHT11< PIN1, PIN2 >::readTemperature ( )

inline

Reads and returns the temperature from the DHT11 sensor.

Returns

Temperature in Celsius, or an error code if the reading fails. Error codes:

• 254: Checksum mismatch
• 253: Timeout

Definition at line 66 of file MiniR4_DHT11.h.

readTemperatureHumidity()

template<uint8_t PIN1, uint8_t PIN2>

int MiniR4DHT11< PIN1, PIN2 >::readTemperatureHumidity ( float & temperature, int & humidity )

inline

Reads temperature and humidity.

Parameters

temperature	Reference to store temperature.
humidity	Reference to store humidity.

Returns

0 on success, otherwise error code.

Definition at line 106 of file MiniR4_DHT11.h.

setDelay()

template<uint8_t PIN1, uint8_t PIN2>

void MiniR4DHT11< PIN1, PIN2 >::setDelay ( unsigned long delay )

inline

Sets the delay between consecutive sensor readings.

By default, the delay is set to 250 milliseconds. This can be adjusted using this method.

Parameters

delay

The delay in milliseconds between sensor readings.
