Hi all,We are using the thermopile sensors to estimate attitude of our airplane. The problem is that the paparazzi wiki mentions a nonlinear relationship between the angle and the voltage. Therefore, we can't use it unless we calibrate it experimentally and find the values for different angles and store them in a table. However, that would be cumbersome. It would help greatly if there was a mathematical relation or a lookup table between the voltage and angle, but so far we haven't been able to find it. Any ideas on this?-yogesh, aravind
