About This Board
ESP32-based PT100 RTD temperature indicator with 7-segment LED display. Uses a MAX31865 precision RTD-to-digital converter for accurate platinum resistance sensor readings. Applies a 10-sample rolling average to eliminate noise. Features three front-panel buttons for a field calibration menu, allowing a ±10°C offset adjustment stored in EEPROM — so calibration survives power cuts. Suitable for cold storage, industrial ovens, food processing, and pharmaceutical temperature monitoring.
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.
