Modular Weather Station
One of the projects I wanted to build for some time was a Modular Weather Station. Modular in the sense that we can add the sensors we want just by changing the software.

Room Monitor for HomeAssistant
After preparing a Raspberry Pi with Home Assistant to manage various spaces, I noticed that one of the basic information of each space is temperature and humidity. We can buy one of several sensors available on the market compatible with Home Assistant or build one of ours. So i decided to create my own room monitor for HomeAssistant.

Server Room Monitor
One of the problems of a server room is the temperature. With different equipment producing heat, this rises quickly. And if the air conditioning fails, it quickly stops everything. To predict these situations we can acquire one of several environmental monitoring systems in the market. Being a simple system, I decided to make a custom solution and build a server room monitor system. Thanks in advance for the support of PCBWay that provided all the necessary pcb’s.

Aquarium Controller using nodeMCU and MQTT
For some time now I wanted to start automating parts of the house. Although several parties are already planned, I decided to start with the aquarium.
Currently the aquarium has two analog timers to control lighting and water filtration. The problem is that whenever there is a light fault, the timers change the lighting and filtering times.
To solve this problem, I decided to install a nodeMCU module, which receives water temperature data through a probe, controls lighting and filtering through a relay, and communicates with the Raspberry Pi that controls all IoT (Internet of Things) through MQTT (Message Queuing Telemetry Transport) messages.

Temperature and Humidity Station with LCD
A few months ago i’ve presented a workshop about Arduino and decided to build a simple meteorological station. The station measure the temperature and humidity level, showing the values on a LCD and on a visual indicator. This indicator as three leds: one blue, one green and one red.
