I ordered some 7cm x 3cm prototype boards a while ago which have just arrived. I will create a few sensor boards and a relay board to make sure everything is working correctly and test out some of the rules for the automation before I do a big parts order for the new house. These will be put in a temporary box until I finalise the design on my 3D printed cases.
Each sensor or controller will have the same basic components which include the arduino nano, the NRF24L01 and a DHT11 as a sensor in the sensor nodes and as a safety feature in the controller units to make sure nothing overheats. I am also making a PCB to hold the basic components with expansion sockets for extra sensors and control devices.
Over the next few days I will create step by step instructions for the basic sensors and controllers. Please let me know what features you would like to see on the sensors and controllers and I will integrate what I can into the prototypes and the first version of the PCB
