The TPA81 from Devantech is a
thermopile array sensor which detects infrared in the 2um-22um
range. This is the wavelength of radiant heat, therefore the
TPA81 is unaffected by ambient light.
The TPA81 can detect a candle flame
at a range of 2 metres.
It has an array of eight thermopile sensors arranged
in a row. The TPA81 can measure the temperature of 8 adjacent
points simultaneously. The module can also control a servo
to pan itself around and build up a thermal image.
Communication with the TPA81 module is via the I2C bus.
This is available on popular controllers such as the
BASIC
Stamp BS2P, as well as a wide variety of microcontrollers.
I2C communications with a PIC microcontroller may easily
be implemented using the
PicBasic or
PicBasic Pro
compilers.
