IFSS-0032InfraredModule

Cellphone and handheld instrument application of Infrared Module

General Information
This Infrared Module is a contact less temperaturemeasuring system based on the detection of infrared radiation.
IFSS-0032 Infrared Module is equipped with an infrared sensor (Thermopile)inits front side. The Thermopile Sensor has to be pointed at the target object.
The basic working principle of infrared module is
1. Detecting infrared radiation with a thermopile sensor
2. Further analogue signal processing
3. Calculation of ambient and object temperature by using a microcontroller

4. Providing ambient and object temperature as digitaloutput (SPI Operation)

Specifications
Object temperature range: 0~100C
Accuracy:2C or 2%
D:S: less 3:1
3.3Vsupply
SPI output
Tiny size

Field of View
The diagram below shows the measurement spot size depending on distance tomeasured surface.
The maximum distance to measure the surface temperature of an object depends onthe field of the sensor (90) and the surface size of the object. To ensurecorrect measurement, the surface size needs to be at least as large as the spotdiameter to fulfill the complete field of view of the sensor.
i.e.: Distance to object surface: 10mmMinimum diameter of object surface: 20mm
i.e.: Distance to object surface: 50mmMinimum diameter of object surface: 100mm
