lookup table for thermopile sensor

How to create lookup table - Programming Questions ...

· How do I go about creating a lookup table: I need to output temperature based on adc readings and the sensor i am using is not linear so i cannot simply calculate out the temperatures. Here is a rough example of the temp vs voltage i need. Temp Voltage 50° F (10° C) V DC 68° F (20° C) V DC 86° F (30° C) V DC 104° F (40° C) V DC 122° F (50° C) V DC 140° F (60 ...

US20180217292A1 - Use of thermopiles to detect human ...

A method of detecting presence and location uses sensor data received from a plurality of thermopiles, each thermopile having a different field of view. In response to detecting a change in the sensor data, stored background values for each field of view are accessed and then the location of a body ( a human or animal) is determined based on differences between the sensor data and sensor ...

A tutorial on lookup tables in C « Stack Overflow

· Well a lookup table is simply an initialized array that contains precalculated information. They are typically used to avoid performing complex (and hence time consuming) calculations. For example, it is well known that the speed of CRC calculations may be significantly increased by use of a lookup table. A suitable lookup table for computing the CRC used in SMBUS calculations is shown …

Thermopile Power Sensor - Newport

Thermopile optical power sensors are based on thermocouples. A thermocouple consists of two dissimilar metals connected in series. To detect radiation, one metal junction is typically blackened to absorb the radiation. The temperature rise of this junction with respect to another non-irradiated junction generates a voltage. Our thermopile power sensors offer broadband, spectrally flat response ...

Technical data thermopile sensors - Mantech Electronics

A thermopile sensor generates a voltage, which is proportional to the incident infrared (IR) radiation power. Because every object emits IR radiation with a power, which is a strict function of its temperature, one can deduct the object’s temperature from the thermopile signal. This method is called pyrometry. PerkinElmer’s thermopile sensors [1] are perfectly suited to be employed in ...
