Our module irradiates atmospheric dust going along the sensor with light of the LED and detects the borrowed light. When atmospheric dust absorbs moisture , particle size of dust with less than it of detectable particle size becomes big. As a result, particle size of dust with less than it of detectable particle size becomes in a detectable particle size range, and it is necessary to revise a density coefficient.

Please design the circuit considering that output voltage of the dust sensor output decreases by decrease of the light emitting diode output (or less 50% / five years) if the dust sensor is used for a long time. 5 Product No. Sheet No. PAGE ESH-14601B 23/26 7.5 (Disassembly) Do not disassemble this product by removing the tapping screw, etc. After disassembling, the standard value of the specification may be not satisfied even if it is assembled again. 7.6 (Influence of noise) If the noise source such as an electrostatic precipitator is placed near the sensor, the sensor output may change by the induction noise . And, the sensor output may change by the noise of the power line. Please use this product after fully confirming the effect of the noise source on the sensor output. 7.7 (Influence of vibration) The output of this product may change by the mechanical vibration. Please use this product after fully confirming that there is no problem in practical use. 7.8 (Influence of outside light) If the outside light enters from the dust passa ge hole, the output may be affected. For example, please consider it so that this module is placed on inner side of the instrument to prevent this product from being affected by outside light. 7.9 (Dew condensation) When dew condensation occurs in the sensor inside, the sensor does not work normally. Please consider it so that dew condensation does not occur. 5 Product No. Sheet No. PAGE ESH-14601B 24/26 7.10 (For the Installations location) The dust will come out from the fan enters through an intake hole (on the side opposite to the fan). Please install this module in a good place for a wind flow, not interfere with air flow. And please design that the air intake of case is installed upward for less dust. In addition, I consider that there are the connection cable with the module and a fan tie line, and, please attach it. 7.11 (For a surrounding environment) Will cause a performance degradation by to be entered dust, insects, oil, etc into this module.

This module is recommended for the intermittent operation for long life. By operating the fan only when measuring PM2.5 material, a fan life is extended and the dust will be hard to collect. And We strongly recommend intermittent operation. ON time for intermittent movement of the fan : Min. 10 seconds. But the customer lengthening ON time can get a more stable value. Please set it to the design specifications of the customer in OFF time for intermittent movement of the fan. In addition, it is possible by stopping intermittently a fan, to be used as a dust sensor. 5 Product No. Sheet No. ESH-14601B PAGE 26/26 (Others) 8.1 (Country of origin) () China (Wuxi) 8.2 (Production site) WUXI SHARP ELECTRONIC COMPONENTS CO.,LTD Address : WUXI NATIONAL HIGH & NEW INDUSTRIAL DEVELOP MENT ZONE No.60 AREA,MINSHAN ROAD,214028, WUXI CITY, JIANGSU PROVINCE, P.R.CHINA 8.3 Phone :86-510-5228493 Fax :86-510-5229753 Production factory and Outgoing quality assurance 751-8522 Outgoing quality assurance department QUALITY ASSURANCE DEPT SYSTEM DEVICE DIVISION ELECTRONIC COMPONENTS AND DEVICES GROUP SHARP CORPORATION Address : 1,ASAHI DAIMON-CHO,FUKUYAMA,HIROSHIMA,751-8522,JAPAN Phone :0849401652 Fax :0849401729 8.3 (Advance notice of change) In case of any change necessary for the specification, materials, production process and control systems, the request for change shall be sent to the engineering department and the Reliability control section in writing, with quality and reliability confirmation data with it. 5
