Infrared obstacle avoidance: a beam of infrared rays directly in front, when there are obstacles in a certain distance, the object will reflect back a part of the infrared. Collect and detect the presence or absence of reflected infrared, you can know whether there are obstacles ahead and make avoidance actions.
Infrared line inspection: Use infrared thermometer to inspect the fault point of the power line. When the power line has a bad contact fault, the fault point is usually accompanied by a temperature rise. Infrared thermometers can remotely measure the temperature of every place on the line and find the fault point.
The principle is that the fault point with high temperature will emit a higher level of infrared radiation, which is measured by the infrared detection chip after being focused by the optical system of the thermometer, and the fault location and severity can be determined after comparing with the ambient temperature.
Flame sensor: A sensor used to detect the presence or absence of flame. Flame sensors vary according to how far they are being detected.
For forest fire prevention such a large range of flame detection, is still the use of special infrared photosensitive tube, when the region appears significantly higher than the ambient temperature of the infrared source point, indicating that the point appears open flame; For the detection of very close flames (such as for automatic combustion equipment), the characteristics of low resistance in the flame region and high resistance in the non-flame region are used for detection.
