Sensirion STS41A series automotive-grade temperature sensors deliver high accuracy (±0.2°C typical), fast response times, and robust reliability.
Quick unboxing of the kit, how to connect it and capture real time CO2 Data, for indoor smart air quality and IoT applications.
If the flow of gas is too low, inadequate shielding generates porosity, oxidation, and weak welds. If the flow of gas is too high, turbulence sucks in air with the same result.
To protect occupants, international regulations like GTR 20 and GB 38031-2025 mandate early detection of such dangers and timely warnings to ensure safe evacuation. Meeting present and future requirements demands reliable sensor technology.
