Optical Sensors & Detector – Transducer for Photodiodes
Digiboard
Digiboard Digital Interface Board for Intelligent Signal Processing and Multi-Sensor Data Integration in UV Systems
The Digiboard is a digital interface and processing board engineered to connect, manage, and process signals from multiple UV and optical sensors with high precision.
Designed to complement SGLUX photodiodes, AMPCON amplifiers, and TW-MF2CAB Multiboards, the Digiboard converts analogue signals into accurate digital data for UV irradiance, dose, and Index computation.
Featuring a high-resolution ADC, onboard microcontroller, and USB / RS-485 / Ethernet communication options, it enables real-time monitoring, calibration, and system integration.
The Digiboard supports Modbus RTU and MQTT protocols, making it compatible with IoT networks, data loggers, and industrial control systems.
Compact, configurable, and temperature-compensated, it ensures traceable, stable, and interference-free digital signal processing, delivering exceptional reliability for scientific, environmental, and industrial UV measurement systems.
Understanding Digiboard
The Digiboard acts as the digital backbone of UV measurement systems, converting amplified photodiode outputs into high-precision digital signals.
It supports up to four independent sensor inputs, each with programmable sampling, filtering, and scaling options.
A built-in microcontroller performs real-time signal processing and communicates the results to external control units, data loggers, or cloud platforms.
When integrated with AMPCON and TW-MF2CAB, the Digiboard forms a complete, modular UV sensing chain — from signal detection to digital communication.
Its robust firmware ensures error-free communication and calibration traceability, making it indispensable for automated, networked UV monitoring systems.
