    Can't say much but its working great. I'm using it for our robotics project. A line follower robot.
    Glad I bought it last December because it took about a month for shipping.

  • Good Sensor

    posted by himan14

    •Good build quality!•Better price!!•Free shipping!!!•I checked the sensor range up to 50 cm and working properly. I have not tested the limit of 80 cm indicated in the product information.•The sensor has a screw in the back to adjust the detection range•A red LED on the back lights up when an obstacle within its range.
    •The sensor's detection distance varies with the color of the surface which reflects light. In a dark surface, the detection distance tends to be shorter from the initially set.•Include some terminals on the wires would be a good idea.
    •The device does its job at an unbeatable price!
  • cheap and good

    Device is small,good quality,easy to setup....it can be turned on and off with SMS...which makes it ideal for securing far objects such as cotage or garage...if the sensor is activated it will call you on predefined number so you can listen what is going on there.....the device covers the area 5-8m in front of sensor (90 degrees)
    It can be on charger all the time,also it can be connected with the solar charger if you dont have electricity on the place where you put the device
    Great device which can be used for different purposes

    It is very good goods. All works. All functions are present. This that that I wanted.
    Passive infra-red detector IS-215 / IS-215T the companies Р&- Systems (trade mark IntelliSense) provides reliable detection at the reasonable price. The optical system forms the dense diagram of an orientation with a zone of detection 12 х 12 meters, including two petals, directed directly downwards under the detector. IS-215 / IS-215T has the gauge of opening of the case, it is steady against influence of white light and a radio noise. The detector is compact, attractive, simple in installation and service. It can be established{installed} inside of a protected premise{room} both on a wall, and in a corner without an arm or on an arm.
    All works. All functions are present. This that that I wanted.
  • Works fine, no adjustment pot

    posted by ed2096

    Works as advertisedVery wide detection angle (120)Cover pops off if you don't want it5A relay useful for driving things like LED stripsSeparate wire for PIR sensor makes it more flexible
    Will stay on as long as there is movementNo protection against flipping on/off constantly (e.g. minimum off period)Consider another model that has an adjustment pot if you need itOnly tested relay using 12V source
    Cheap, worth buying if you can deal with minor limitations, easier than building your own
