Description

SP18396 Heimann Sensor HTPA32x32d Thermopile couv flyerA small, easy to use, low-power, cheap non-contact temperature measurement for varying applications.

LWIR imaging is increasingly used in myriad applications, from consumer to industrial. Low-cost, large arrays (32 x 32 and more) are specifically adapted to smart home/smart building applications for occupant detection, popu-lation localization, population counting, fire detection, and more. For these large markets of many hundreds of millions units a year, thermopile sensors are cost-competitive compared to micro-bolometers.

 

SP18396 Heimann Sensor HTPA32x32d Thermopile 2

Based on a low-definition, 32 x 32 thermopile sensor, Heimann Sensor’s HTPA32x32d is dedicated to these markets. Cheaper than a microbolometer and easier to integrate, the thermopile offers very good performance for applications that do not require high-resolution images and a high frame rate.

The thermopile array sensor consists only of a 0.5cm³ camera (with lens). The system is made easy for integrators with a digital I²C interface, and includes for the first time a silicon lens for low-cost applications. The 32 x 32 array sensor uses a 90µm pixel based on a thermopile technology for a very compact design.

This report provides a detailed teardown and cost analysis of the thermopile die, the silicon lens, the EEPROM die, and the packaging.

This report also includes a comparison between the characteristics of the new and previous versions of the thermopile sensors from Heimann Sensor, and a comparison with FLIR’s ISC1403 microbolometer. This latter comparison highlights differences in each company’s technical choices.
