Checkpoints relating to principle of operation MP motion sensors are passive infrared sensors which detect changes in the infrared rays. They may fail to detect successfully if a heat source other than a human being is detected or if there are no temperature changes in or movement of a heat source. Care must generally be taken in the following cases. The performance and reliability of the sensors must be checked out under conditions of actual use. <1> Cases where a heat source other than a human being is detected. 1) When a small animal enters the detection range. 2) When the sensor is directly exposed to sunlight, a vehicle’s headlights, an incandescent light or some other source of far infrared rays. 3) When the temperature inside the detection range has changed suddenly due to the entry of cold or warm air from an air-conditioning or heating unit, water vapor from a humidifier, etc. <2> Cases where it is difficult to detect the heat source 1) When an object made of glass, acrylic or other subject which far infrared rays have difficulty passing through is located between the sensor and what is to be detected. 18 2) When the heat source inside the detection range hardly moves or when it moves at high speed; for details on the movement speed, refer to the section on the performance ratings. 2. When the detection area becomes larger When the difference between the ambient temperature and body temperature is large (more than 20°C 68°F), detection may occur in isolated areas outside the specified detection range. 3. Other handling cautions 1) Be careful not to allow dust or dirt to accumulate on the lens as this will adversely affect the detection sensitivity. 2) The lens is made of a soft material (polyethylene). Avoid applying a load or impact since this will deform or scratch the lens, making proper operation impossible and causing a deterioration in its performance. 3) The sensor may be damaged if it is exposed to static with a voltage exceeding ±200V. Therefore, do not touch its terminals directly, and exercise adequate care in the handling of the sensor. 4) When the leads are to be soldered, solder them by hand for less than 3 seconds at a temperature of less than 350°C 662°F at the tip of the soldering iron. Avoid using a solder bath since this will causing a deterioration in the sensor’s performance. 5) Do not attempt to clean the sensor. Cleaning fluid may enter inside the lens area causing a deterioration in performance. 6) When using the sensors with cables, it is recommended that cables which are shielded and as short as possible be used in order to safeguard against the effects of noise. For the general precautions, refer to the Notes for Motion Sensors on page 27.
