About This Board
ESP32-based programmable counter board with integrated relay output. Operates in three states: Standby (display off, relay idle), Progressing (counter decrementing from a set target, display active), and Threshold (relay state changes when the counter reaches the set threshold, yellow/alert indicator shown). Once the count completes, the board returns to standby. Controlled over WiFi from a phone or laptop browser. Suitable for batch counting, production run tracking, dose counting in dispensing systems, and any application requiring a counted relay trigger.
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.
