NODEMCU SMART TIMER HOW TO

Secondly, objects are created for these libraries, LiquidCrystal_I2C lcd(0x27, 16, 2) Serial.println('Failed to read from DHT sensor!') įirstly, libraries are included. Control home appliances manually without internet. Monitor real-time feedback in the Blynk App. Control home appliances with WiFi (Blynk App) Control home appliances with manual switches. Now, run this app and click the “New project” button.ĭHT dht(D3, DHT11) //(sensor pin,sensor type)Ĭhar auth = '' //Enter the Auth code which was send by BlinkĬhar pass = '' //Enter your WIFI Password This ESP8266 NodeMCU control smart relay has the following features: Connect multiple NodeMCUs with the same Blynk account. First, download and install the Blynk app into the smartphone.Thirdly, let’s set up the Blynk app step by step. To do this, use the circuit diagram below. Jumper wires - Amazon / Banggood Step 1.

Also, those values can be seen on the interface of the Blynk app and on the LCD. And then, the Nodemcu board receives values through the DHT11 sensor. The Nodemcu board connects to the Blynk app through the internet and Blynk cloud. When there is no timing tasks to do, timer will stop the internal counter automatically. We can use this system mainly for animal farms, greenhouses, and factories. nodemcu-timer includes only four APIs : setTimeout (), clearTimeout (), setInterval (), clearInterval ().

Also, since this project belongs to IoT technology, we can monitor temperature and humidity from anywhere in the world through the smartphone or tablet. The DHT11 sensor is mainly used for this project.
