4CH_TIMER_RELAY

This ESP32-C3 based 4-channel relay timer controller provides reliable AC load automation with precise scheduling capabilities. Featuring a DS3231 RTC for accurate timekeeping and MOSFET-based AC input sensing for manual override, the system can switch four independent 10A AC loads according to programmed daily schedules, countdown timers, or cyclic patterns. The design incorporates safety features like optical isolation and proper PCB spacing while offering Wi-Fi connectivity for remote configuration through a web interface, making it suitable for home automation, industrial control, and agricultural applications.
