  • May 02, 2019 · Ultrasonic Sensor is used to calculate the distances of the obstacle. It works on the principle of SONAR. Ultrasonic Sensor senses the distance of an object by sending the ultrasonic sound at 40,000 Hz, which travels through the air and if there is an object or obstacle on its path it will reflect or bounce back to the receiver of the module.
  • Sep 07, 2017 · IOT with Blynk and NodeMCU I have just bought a new board, the NodeMCU ESP8266 ESP-12 Devkit 0.9. This board has more GPIO than the ESP8266 ESP-01, so you can attach more components to it. This is also an Arduino-compatible board, and you can upload sketches to it via the Arduino IDE.
  • Aug 18, 2019 · IoT Security System- In this tutorial, you will learn how to make your own IoT based home/office security system using the Nodemcu ESP8266 Wifi module, PIR Sensor, Infrared Sensor, and Blynk application. Each time an Intruder is detected a notification message is sent to the Blynk application. This is a real-time IOT based Security system.
  • Apr 20, 2020 · hy guys, can you help me to try your project about ultrasonic sensor use NodeMCU and Node-red? i want to monitoring ultrasonic sensor with Node-red use NodeMCU (MQTT) but i have no get the tutorial.
  • Apr 15, 2017 - In this tutorial we will make "WiFi Deauther " using NodeMCU ESP8266. We will use the "ESP8266 Deauther" source for this. The source is shared by "spacehuhn"...
  • Oct 18, 2020 · Blynk App, temperature sensor, and LDR. Here RST pin is active low, so the Touch sensor connected with the RST pin should be active low. Download the attached Code for this NodeMCU project. I have mentioned all the links of the required libraries in the code.
  • อุปกรณ์ที่ต้องใช้ใน บทความ สอนใช้งาน NodeMCU ESP8266 เริ่มต้นใช้งานติดตั้งโปรแกรม blynk. NodeMCU V2 LUA based ESP8266-12E; สาย Micro USB Type B to USB 2.0 Type A ยาว 1 เมตร
  • You can use any sensor available to you as long as its output voltage is not more than the recommended maximum of 3.3 V. The ESP8266 itself accepts only up to 1 V on its analog pin. Thankfully, the NodeMCU board has a built-in voltage divider. The ESP8266 (which is the main chip on the NodeMCU) uses a 10-bit ADC.
