This circuit integrates an ESP8266 NodeMCU microcontroller with four IR sensors and two I2C LCD displays. The NodeMCU reads signals from the IR sensors and outputs status information to the LCDs. It is designed for applications requiring multiple proximity detections with real-time visual feedback.

Learn how an IR sensor works with the ESP8266 nodemcu development board by just following the given easy steps.

Jun 1, 2021 · In this tutorial, learn how to interface IR sensor module with Arduino or ESP8266 or ESP32 to build an accurate Tachometer which measures RPM of a rotating object and display the measured values on 16×2 LCD display module.

Learn to control I2C LCD with ESP8266 along with pinout, wiring, finding I2C address, adjusting contrast, ESP8266 code, create and display custom characters.

Jul 12, 2022 · How to interface IR sensor with ESP8266 (Node MCU) An infrared sensor (IR sensor) is a radiation-sensitive optoelectronic component with spectral sensitivity in the infrared wavelength range of 780 nm … 50 µm.

Connecting IR sensors to a NodeMCU is really simple. The IR acts as a digital output so all you need to do is operate the pin to flip high (detected) or low (not detected). Check out the images for more details.

Feb 10, 2023 · Here, we will interface MLX90614 Sensor with NodeMCU ESP8266 & 0.96″ OLED Display. We will connect the ESP8266 to the WiFi Network & send the temperature data, i.e Ambient Temperature & Object Temperature to the Blynk Application Dashboard.

Jun 22, 2016 · This tutorial will demonstrate how to connect a 16x2 LCD display using I2C to an ESP8266 NodeMCU dev kit. The LCD display I'm going to use is fairly common and can be picked up for a couple of bucks from Amazon .

To do this, we will use in this project an ESP8266 nodeMCU, an MLX90614 infrared sensor, and an OLED 96 "display, which will display the temperature data. The MLX90614 infrared sensor used in this setup is actually a type of camcorder.

Sep 12, 2022 · Tutorial on how to use Infrared Sensor Obstacle Avoidance with Arduino, Nodemcu ESP8266. And Explanation of how the sensor works.
