Description:MP503 gas sensor is for air quality. It adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature 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 gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas concentration.
Features:Model: MP503Sensor Type: Semiconductor flat-surfaced sensorDetection Target: Alcohol, SmokeStandard Encapsulation: Metal CapDetection range: 10ppm ~ 1000ppm(Alcohol)Loop voltage: 24VdcHeating voltage: 5.0V±0.1V (AC or DC)Load resistance: AdjustableHeating resistance (RH): 95Ω±10Ω (Room Tem.)Heating consumption (PH): ≤300mWSurface resistance (RS): 1KΩ ~ 30KΩ (in 50ppm Alcohol)Sensitivity (S): Rs(in air)/Rs(in 50ppm Alcohol) ≥5Concentration slope (α): ≤0.6(R100ppm/R30ppm alcohol)Warm-Up Time: More than 48 hoursPin Number: 4 PinOperating Temperature: 20℃ ±2℃Operating Humidity: 65% ±5% RH
Applications:It is used on occasions such as household and office for harmful gas detection, automatic exhaust device, air cleaner&etc.
Package Include:1 x MP503 Air-Quality Gas Sensor
