Principle Introduction
| The sensing material of MEWOI-MIX1012 Smoke Detection Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the Smoke gas exists, the conductivity of the sensor will be raise according to the gas concentration goes up. Through a simple circuit, to convert the changes of conductivity to correspond to the gas concentration. |
Features
High sensitivity Low cost, long life Low power consumption Good stability Simple application circui |
Application
Smoke detector Portable gas detectors |
