I have started a new build of some PIR sensors for Mindstorms and have some available if anyone is interested in adding a "human" detector to their Mindstorms projects.
I'm not sure what the rules are here about posting $ items, so just posting the spec's (mssg me if interested);
NEW in V2;
· PCB layout for interface circuit
· Lego electric connectors (no machined connectors)
· Faster PIR sensor!
· Smaller enclosure
With these improvements the sensor now has a more rugged construction, can be modified to fit your needs (placed in other enclosures), is easily connected to Mindstorms cables/RCX/NXT, and is FASTER! With a reset time of less than 1 second, your creations can now quickly react to people and do other tasks.
Detecting Range = 7m (23 feet)
Detecting Angle = almost 180 degrees (front side of sensor)
Standby current = less than 50uA (very low power)
Active current = less than 3mA when active (ON and person detected)
Working Temperature = -15degC to 70degC
Trigger Delay = less than 1 second
Dimensions = 1.8 inches x 1.25 inches x 1.25 inches
(or in Lego terms : 6 studs x 4 studs x 3 bricks)
This is a custom built, low power PIR sensor for use in Lego Mindstorms Robotics projects. It consists of an off-the-shelf PIR module, standard interface circuit, Lego blocks enclosure, and Lego electric contacts to be connected to your Mindstorms RCX or NXT brick. Each unit has been built, tested and ready for use!
