One project that i needed to complete with some urgency was a baby monitor. There are several types of monitors on the market, but the IP based monitors are expensive and the others don’t have enough range. There are several types of projects for baby monitors on the internet but none as wanted. Because of this, I decided to build my version.
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.
