firstly, hello everyone. 
.i'm new forum , wanted know how connect tgs4161 sensor arduino uno ?? please post pictures. have tested code circuit given in figaro datasheet showing 16.67 constantly.

the sensor (without supporting circuits?) connects hi impecance analog input (>100 gohm)
arduino analog inputs in range 0.1 gohm, connecting directly may not good.
an opamp (voltage follower) must used.
if math correct, scr.shot.4 looks ok
