Lighting and Basic Home Automation

Changing a lamp seems easy until the living room turns dark, the kitchen turns bluish and the dimmer makes the LED flicker. This course teaches you to do lighting with judgment. You will read the LED package (lumen, watt, efficacy, color temperature, CRI, lifetime, Inmetro mark) and calculate how much light each room needs using the simplified lumens-per-square-meter method, with NBR ISO/CIE 8995-1 (the Brazilian standard, derived from ISO/CIE 8995-1) as a reference. Then you will build the controls every electrician must master: single-pole switch, two-way and intermediate switch, occupancy sensor, photocell and dimmer, with the compatibility rules that prevent flickering LEDs and burned-out sensors. In the last module you enter basic automation: Wi-Fi smart switch, relay module, the neutral in the box, the customer's network, scenes and routines, and how to build an honest proposal per room. There are 6 lessons with examples from homes, small businesses and farms in the interior of São Paulo state, a field checklist and a final project to light 3 rooms. The course does not replace a professional lighting design and does not teach building automation.
