About This Board
ESP8266-based clock-scheduled relay timer using a DS3231 RTC module. Unlike a cyclic timer, this board turns the relay ON at a specific time of day and OFF at another specific time — making it ideal for daily scheduled automation like morning/evening lighting, HVAC switching, irrigation, or equipment startup/shutdown. Set ON time, OFF time, and sync the RTC clock all from the built-in WiFi web interface. The DS3231 RTC keeps accurate time through power cuts. Also reports the DS3231 onboard temperature sensor reading.
All Comet Instruments LED boards are designed and manufactured in-house at our Indore facility. Each unit is tested before dispatch. Firmware is open for customisation on request. Bulk pricing available for orders of 5+ units.
