I am using a WeMos Wifi ESP8266 with a DHT11 sensor to measure temperature and humidity in my house and send them to SinricPro. Alexa then reads from here and uses them to answer to the question "...
I was trying to display the readings of my dht11 sensor on the Blynk dashboard but I am struggling a lot. A little help would be really appreciated.#define BLYNK_PRINT Serial/* Fill in information ...
So I've been trying to get a small project set up for the upcoming eclipse, just to read changes in the humidity and temp during the eclipse.I have two DHT11 sensors, I'm only using one.I have ...
I am exemining code for DHT11 from CircuitGeeks, variant without using lib. The problem is a mismatch between DHT11/DHT22 protocol and signals, which are read from sensor in scetch. Despite this, ...
I want print data from a DHT11 (temperature and humidity) on a MAX7219 LED display but it only shows 0. Serial monitor, on the other hand, shows both humidity and temperature which means that my ...
I'm trying to get my ESP32 internet clock to show temperature and humidity data from a dht11 sensor on a MAX7219 display but my code seems to have some issues. After verifying the code there are no ...
I need to update DHT sensor data to the webserver in JSON format using ESP8266. This is my code.#include <ESP8266WiFi.h>#include <WiFiClient.h>#include <ESP8266WebServer.h>#...
I have a problem with my project, the problem is that my Firebase can't detect my DHT11 temperature and humidity sensor from the Arduino.The code runs without an error but the Firebase can't read my ...
The setup includes an WEMOS/ESP8266 R1 mini compatible board, a DHT11, a photo resistor and a magnetic reed.The libs used are:#include <ESP8266WiFi.h>#include <PubSubClient.h>#include &...
I’ve got a question about this code I’ve attached please- would it be correct to read it like this:After defining the variable temperature and humidity and assigning measurement_timestamp to millis(),...
I had a mini project with a DHT11, a temperature and humidity sensor, working perfectly on my Arduino UNO clone. Then, I bought a power supply board, that can feed the sensor with the 5V it requires, ...
The following code reads the DHT22 temperature and humidity values, assuming the pin value as the sensor's host pin.When the temperature drops below 0°C, this code returns inadequate values in the ...
Hello. I've got a question about DHT11 sensor. Why should pullup resistor be connected as on the image below:while as far as I know, pullup resistor should be placed between Arduino 5V pin and Vcc ...
void Sensor_value(){ server.handleClient(); humidity = dht.readHumidity(); temperature = dht.readTemperature(); }I want to make condition if temperature = null and Humidity= null ...
