Note the use of pyroelectric sensor material with temperature changes in the polarization characteristics of detecting infrared radiation, double-sensitive yuan complementary methods inhibit the interference temperature changes, the work of improving the stability of the sensor.
Use 1, the characteristics of indicators in the source resistor R2 = 47K Ω conditions of the users use of sensors, can be adjusted according to their own needs R2 size.
2, attention to the sensitive yuan depending on the location and market size, in order to get the best optical design.
3, all voltage signals are used in the measurement of a peak-calibration. B balance of the EA and EB respectively, said the two sensitive yuan peak voltage output signal a peak.
4, the use of sensor, the pins bending or welding positions should be left pin 4 mm above the base.
5, the use of sensors, information brochures should, in particular, to prevent the wrong pin
