MP503 gas sensor is for air quality. It adopts multilayer thickfilm manufacturing technology. The heater and metal oxidesemiconductor material on the ceramic substrate of semiconductor material on the ceramic substrate of  

Al₂O₃ are fetched out by electrode down-lead,encapsulated in metal socket and cap. Conductivity of the

sensor is affected by the concentration of target gas. The higher the concentration is, the higher conductivity of sensor conductivity into output signal corresponding to gas gets. Users can adopt simple circuit to convert variation of concentration.           

Features
