In this guide, we will learn to interface GY-906 MLX90614 non-contact infrared temperature sensor with ESP8266 NodeMCU. The MLX90614 is a contactless IR Temperature sensor which can measure temperature without even touching the object. This exceptional sensor introduced by Melexis uses IR technology that uses the IR radiations to measure temperature and provides a digital … Read more
In this ESP32-CAM tutorial, we will use machine learning techniques to build an image classification project using ESP32 CAM. The ESP32-CAM will be used to capture an image which will then be identified using a trained Machine learning model. For this project, we will use Clarifai’s image recognition AI models. Recommended Components The following components … Read more
In this user guide, we will learn how to publish sensor readings to ThingSpeak using Micropython and ESP32. We will use Thonny IDE to program our ESP32 board which will be connected to a temperature, humidity, and pressure sensor. Our main aim is to transmit these sensor readings to ThingSpeak easily and interactively demonstrate them. … Read more
In this user guide, we will learn to build ESP32 Gauges Web server using Server-Sent Events (SSE). Using this technique, we will build an ESP32 controlled web server that will automatically update sensor readings such as temperature and humidity to all connected web clients and display them in linear and radial gauges. Any appropriate sensor … Read more
