The TPA81 is a thermopile array for infrared detection in the 2um-22um range. This is the wavelength of the radiation heat. The pyroelectric sensors commonly used in burglar alarms and for switching on outdoor lights detect infrared in the same wavelength range. However, these pyroelectric sensors can only detect a change in heating output - they are motion detectors. Although useful in robotics, their applications are limited because they cannot detect and measure the temperature of a static heat source. It has an array of eight thermopiles arranged in a row. The TPA81 can measure the temperature of 8 adjacent points simultaneously. Can also control a servo to move the module and build a thermal image. The TPA81 can detect a candle flame at a distance of 2 meters (6ft) and is unaffected by ambient light!
