The Seeedstudio Grove Mini PIR Motion Sensor is a compact, low-power, cost-effective PIR sensor suitable for applications with relatively less detection distance requirements. The sensor's sensitivity is adjustable, there is a reserved pin out on the back of the board so that you can solder a slide rheostat to adjust the sensitivity. If you think the sensitivity is insufficient, here is a trick, dragging the plastic cap a little up will help enhance the sensitivity.
