Detailed Description

DHT Task Implementation File.

This file contains the implementation of the dhtTask function, which is used to handle DHT sensor operations in a FreeRTOS task. The task is responsible for reading temperature and humidity data from the DHT sensor and sending it to a queue for processing.

Function Documentation

dhtTask()

void dhtTask

(

void *

parameter

)

DHT Task function.

This function handles DHT sensor operations in a FreeRTOS task. It reads temperature and humidity data from the DHT sensor and sends it to a queue for processing. The task runs in an infinite loop, waiting for data to be available in the queue. When data is received, it is sent to the network for processing.

isValidDHTReading()

bool isValidDHTReading	(	float	temp,
		float	hum )

Check if DHT reading is valid.

Parameters

temp
hum

Returns

true

false
