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...

Recently the hobbyist market has seen the appearance of the Air602 low-cost ARM WiFi module. This module might be a potential competitor of ESP8266, another low-cost powerful WiFi module, that took the electronics hobbyists by storm long ago and is still extremely popular. But what's...

The ESP8266 had been in the tech scene for over four years now and has seen various competitors like the RTL8710 or, more recently, the RDA5981. But none of them has really been able to knock off the ESP8266 from its throne. The ESP8266 is seen by most as being “good enough.” So the...

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...

Guide to ESP32 with multiple DS18B20 temperature sensors from Random Nerd Tutorials: This guide shows how to read temperature from multiple DS18B20 temperature sensors with the ESP32 using Arduino IDE. We’ll show you how to wire the sensors on the same data bus to the ESP32, install...

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...
