Idea for this project came with my new small fish tank.
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my Cubieboard2 with Linaro Lubuntu, but at the same I wanted to upgrade the packages since the Lubuntu 12.10 is quite outdated.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[…]
