Note: 1. After the sensor is powered on, it needs to warm up about 20S, the measured data is stable, the sensor heating is normal, because the internal electric heating wire, if it is hot, it is not normal. 2. Long term exposure to harsh environments. Whether the sensor is energized or not, if exposed to high humidity, high temperature, high pollution and other adverse environments for a long time, will seriously affect the performance of the sensor.
