A complete home automation system developed on ESP32 microcontroller using freeRTOS. The system is controlled wirelessly via Bluetooth with an android app developed using MIT App Inventor.

CHPC: Cheap Heat Pump Controller

Automatically water plants based upon moisture sensor feedback.

This repository contains example code useful when using the WaveShare 8-channel relay module for the RaspberryPi. The example code provided by WaveShare is mixed up and doesn't work correctly.

This is an Alarm Clock (Radio) based on the ESP8266 in combination with a MAX7219 LED-Matrix, Relay-Board and DS3231 RTC.

IOT Systematic and Automated Regulation of Irrigation systems for Backyard farming Operations using NodeMCU v3

Arduino code to control the Step of a motorhome. Arduino + motion detector (MPU-6050) + relay + ultra low power

esp8266, four relays, 2 DHT11: Individually Turn on/off four relays to control two heat pads and a humidifier based on reading from two DHT11 sensors. Web Page shows values updated using WebSock and a settings web page for user provided threshold values.

T-RelayS3 Signal K project

Routines for managing switches and output relays connected to Arduino/Teensy microcontrollers

IOT PROJECT

Esp8266 relay controller

Refurbished traffic light operating on an Arduino Uno with adjustable light modes and settings via rotary encoder.

This is a code that can be used to control relays with push buttons and MQTT. It gives the user a lot of flexibility to customize the code to fit their own needs. I think it would be a great tool for anyone looking to build their own solutions for controlling relays.

Particle Photon Code for the related Android App

Wifi relays board, NodeMcu based

remote control of 3 relays by SMS using an ESP32 and a GSM800 module; relays are used to turn power plugs (230V) on and off; BME280 to get temperature/humidity to launch e.g. an anti-freeze program with a heater on plug 1

Code to control a Presepe automatically via two arduino boards
