Interesting design information form Texas Instruments. I hope some commercial party will start building these PIR's soon

Description
The TIDA-00759 TI Design uses nano-power operational amplifiers, comparators, and the SimpleLink™ ultra-low power 2.4GHz wireless microcontroller (MCU) platform to demonstrate a low power wireless motion detector implementation. These technologies lead to an extremely long battery life, over 10 years with a standard CR2032 lithium ion coin cell battery, which could be used for applications including motion detection or lighting control through occupancy detection. The PIR sensor has sensitivity of up to 30-feet with shutdown current of 1.63-µA. The design guide includes techniques for system design, detailed test results, and information to get the design up and running quickly.
