The trigBoard is an IoT project that does one thing - it pushes you a notification triggered by a digital input. Well, it's much more than that, but this is the inspiration. I wanted to design a WiFi board that essentially sleeps most of its life, but when that door switch, flood...

As the popularity of Arduino boards increased, the demand for boards which comes embedded with some of the add-ons used with the Arduino increased. One of the most popular add-ons were the WiFi modules which are used to connect Arduino boards to the internet. Several boards were...

Rui Santos has a great write-up on building a Multisensor Shield for ESP8266, that is available on GitHub: In this project you’ll discover how to design and create a Multisensor Shield for the ESP8266 Wemos D1 Mini board. The shield has temperature sensor (DS18B20), a PIR motion...

Simple LED matrix Clock based on the popular ESP8266 with Real Time Clock module and time synchronization over WiFi from an NTP server. One note on the RTC module, apparently it also has the ability to charge the battery, however that's not a good idea when using a CR2032. One possible...

Yet another ESP8266 (ESP-03) based ultra low power weather logger with 4 sensors. Features Working with two AA battery Ultra low power consumption 4 sensors and 6 measurements: HDC1080 - Temperature & Humidity LPS25HB - Pressure VEML6070 - Ultraviolet...

Dani Eichhorn @ thingpulse.com writes: In this post I’m going to show you how you can monitor the power consumption of your battery driven (ESP8266/ ESP32) device. Measuring the power consumption over a full activity/ sleep cycle is the precondition to optimize your code for a longer...

A MAX7219 driven Display, controlled by an ESP8266 SoC and MQTT This project describes how to connect a MAX7219 to an ESP8266 Chip and let it act as a MQTT client. Its basically my ninHOME Node Firmware where you can optionally add a MAX7219 Display. ESP8266 MAX7219 Dot Matrix Display...
