How to Choose a Gas Sensor? Selection Guide

Sensor selection is one of the most critical engineering decisions in gas detection device development. Choosing the wrong sensor technology cannot be fixed by calibration — it leads to certification failures, false alarms, and high maintenance costs.

Gas Control Panel Development: Hardware and Firmware

A gas control panel is the central unit that collects measurement data from gas detectors deployed in the field, manages alarm decisions, and notifies the operator through auditory and visual means. In this article, we cover the key parameters to consider when designing a 4–20 mA based gas control panel — from ADC input to alarm management, from event logging to EN 50271 compliance — drawing on our project experience.

CO/NO₂ Gas Detection System Design for Parking Garages

Developing a CO/NO₂ gas detection system for closed parking lots requires evaluating interconnected design parameters together — from gas detector hardware to the control panel, from firmware architecture to EN 50545-1 certification. This guide covers sensor selection, analog front-end design, panel hardware, and firmware requirements.
