Node Mcu Sensor Design

This section covers electronics projects based on NodeMCU ESP8266 board. The NodeMCU is basically an open source firmware, and also commonly used term for the popular ESP8266 Development Board, which is a low cost, development board designed for IoT applications.

This instructable will explain how to connect a light sensor and a motion sensor to NodeMCU ESP8266 and push the data to the IoT platform ThingSpeak, with an additional feature of a simple Lux meter. Here are what my sensor network system is supposed to do and how it functions Light sensor LDR triggers LED 1 PIR motion sensor triggers LED 2

In this article we'll show you how to create a wireless sensor node using an inexpensive NodeMCU module. NodeMCU is a tiny, low-cost WiFi-enabled microcontroller that supports direct

A DIY Adventure Through Droid Design, 3D Printing, and electrical engineering. By Mellow_Labs The integration of the Node-MCU,PZEM sensor, Relay and provides the system as Smart Power Monitoring system. Smart power meter provides data for optimization and reduce the power consumption.

The MPU6050 sensor module is a combination of a 3-axis Gyroscope, 3-axis Accelerometer, and Temperature sensor with an onboard Digital Motion Processor DMP. It is used in mobile devices, motion enabled games, 3D mice, gesture motion command control technology, etc. System on Chip produced by Espressif is an integrated design to

The RCWL-0516 is a small, inexpensive sensor that uses microwave radar to detect the presence of moving objects. The RCWL-0516 sensor has a single output pin that goes HIGH when it detects movement. It outputs LOW when no motion is detected. This sensor is many times used as an alternative to the PIR motion sensor.
