PIR Basic Theory
2015 Holtek New Product Presentation >> IoT : Measurement / Security / Sensor >> PIR MCU/PIR Module
► As the sensor detects infrared signal deviation, it can reliably detect the presence and motion of human body infrared radiation.
► The signal must be amplified and converted to a digital signal using an MCU or a DSP before generating an output.

Temperature and Humidity Module
HT6M6121
135
► Humidity Sensor : The anodised aluminum has a layer of porous oxide on its surface. Moisture can penetrate through the gold layer and fill the pores of the oxide coating, causing changes in resistance that can be measured by an electronic circuit.
► Temperature Sensor : Negative temperature coefficient – NTC thermistor. In the NTC type, resistance decreases as its temperature increases. A thermistor is a semiconductor device whose resistance changes based on temperature change.

Smoke Detector Basic Theory
Chamber Chamber
Photo Detector
► The optical smoke sensor is a chamber with an IR LED and a photo diode. The IR LED does not directly illuminate the photo diode.
► If smoke is present inside the chamber, a certain amount of light is scattered so some of the light reaches the photo diode.
