My new project consists of HW with cost under 20€. It is able to accurately measure electric power consumption and sends data via WiFi. Great source of knowledge is openenergymonitor.org which includes also Arduino library.
I have just made a prototype of ESP8266 (ESP-01) IoT temperature & humidity SI7021 sensor and also 2x three pin soil moisture sensors with only 0.006mA (6µA) current drain during the sleep.
I have several IoT sensors at home and now I came to the point that I would like to introduce some solid platform for storing sensor data and visualizing them. This post summarize all platforms[…]
I successfully run DHT22 battery ESP8266 temperature/humidity IoT sensor so my next project is a simple IoT Door Sensor. It is up and running and sending a simple event to my HTTP server via wifi[…]
Since my latest ESP8266 temperature humidity IoT logger project is up and running I have decided to cut the last wire – power. There are more approaches how to make ESP8266 running on a battery,[…]
I learned how to program ESP8266 so I created my first temperature IoT ESP8266 project. I used DHT22 as a temperature and humidity sensor and also I did some testing of power consumption using LIGHT SLEEP[…]
I was inspired by several DIY projects. The ESP8266 WiFi 802.11 b/g/n Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266[…]
I wanted to keep my existing configuration and programs on my Cubieboard2 with Linaro Lubuntu, but at the same I wanted to upgrade the packages since the Lubuntu 12.10 is quite outdated. This post describes[…]
You can find several breadboard adapters for ESP8266 WiFi module or nRF24L01+ RF transceiver and also several DIY manuals how to create your own, but I decided to use my new WiFi WSP8266 and NRD24L01 as soon[…]
Google Blogger is very simple and easy to start with blogs unless you start to think of custom plugins, widgets, tools and more advanced themes. Many of us are following this path that starts in[…]
