Cautions: 1. Please avoid the pressure of its gilded plastic chamber from any direction, during welding, installation, and use. 2. When placed in small space, the space should be well ventilated, especially for diffusion window. 3. The sensor should be away from heat, and avoid direct sunlight or other heat radiation. 4. The sensor should be calibrated termly, the suggested period is not longer than 6 months. 5. Do not use the sensor in the high dusty environment for long time. 6. To ensure the normal work, the power supply must be among 4.5V~5.5V DC rang, the power current must be not less...
