URM37 with Arduino

I bought this great ultrasonic sensor made by DFrobot. The only problem is that it's not so easy to control with arduino. It needs a wake-up signal and communicates via PWM pulse. The great thing is, it has an integrated temp sensor for more accurate ultrasonic readings and a servo controller. The servo movement is operated by the wake-up signal width. Clever.

Probably the best thing for me is that it's cheap. It's like 2/3 the price of a parallax equivalent, except that this has integrated atmega8, temp sensor, etc.
