Student view

How to understand this product.

Build a first automation-control project: turn a timed software rule into an observable physical output.

What you can learn

  • ESP32 control logic
  • Scheduling with an RTC
  • Remote-command handling
  • Control-panel design

A simple project flow

  1. Define a rule or time schedule.
  2. Check the schedule condition.
  3. Switch a relay and report the new state.

Real-world applications

Example projects showing what this product can read, control and report. Each requires the appropriate sensors, connected equipment and application software.

Office lighting schedules

Example: configure an on/off timetable using the RTC. Each relay operates a suitable lighting-control circuit, allowing separate zones to follow different schedules and accept authorised remote commands over Wi-Fi.

Scheduled irrigation pump

Example: run a watering timetable in local firmware. A relay commands a correctly rated pump-starter circuit at the scheduled time; the installed motor protection and process interlocks remain responsible for equipment protection.

Remote equipment switching

Example: a Wi-Fi application receives an authorised command for one of four channels. The controller changes the selected relay state and reports the commanded state; actual equipment operation needs separate feedback if verification is required.
