PIR(Passive infrared) Motion sensor is pyroelectric device can detect human movement by detecting Infrared ray emitted by human body. Operating voltage is 5~25VDC, and output voltage is equal to input voltage. High sensitivity, Easy to install.
When people enter into the sensing range, Motion sensor will output a voltage equal to input voltage, after the delay time, it will output 0V; During the delay time if motion detected, the delay time will reset, and start a new delay time.
Widely used on the Motion-activated lighting, LED strips Security System, automatic sensory device and more.

1. The PIR Sensor requires a 'warm-up' time in order to function properly, about 10 s to1 min, depending on the delay time; during this time, the signal triggered by the module is not stable, after one minute, it will be ready.
2. Don't expose the Sensor Switch to direct sun light /lighting, big wind, or placing near to a heater or air condition.
3. Don't fix the item at a place where there are obstructing material (eg. Glass, dense clothes) which IR cannot get though.
4. Don't fix the motion sensor switch in strong shock or vibration environment.

2. obstacle avoidance, automatic control;
3. the object approaches, there is a perceived
4. traffic control;
5. security, industrial control;
6. artificial intelligence, and research
The basic working principle:
(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;
(3) a signal return, a high level is output through the IO port ECHO, the time duration of the high level is
ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
This module uses the simple method, a control port with a 10US above high level, can wait for high level
output at the receiving port. An output can drive the timer, when this port is low can read the timer value,
this time for the location of the time, can be calculated distance. So constantly cycle test, that can achieve
the measurement of the value of your mobile.

Description: This is the fantastically easy to use sensor from Maxbotix. We are extremely pleased with the size, quality, and ease of use of this little range finder. The serial interface is a bit odd (it's RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. The sensor provides very accurate readings of 0 to 255 inches (0 to 6.45m) in 1 inch increments with little or no dead zone!
Maxbotix is offering the EZ0, EZ1, EZ2, EZ3, and EZ4 with progressively narrower beam angles allowing the sensor to match the application. Control up to 10 sensors with only two pins! Checkout the Maxbotix FAQ listed below.

Lowest new price: $13.49
List price: $13.49
Note: 1. The Optimum voltage range is 6~36VDC.
2. It is recommended that the actual detection distance is less than 70% of the detection distance on the name plate.
3.When wiring, do not energized, strictly according to the wiring diagram.
NOT ALL MATERIAL ARE SUBJECT TO THE 10MM DETECTING RANGE.
3 factors that affect the function of the sensor:
1. Material density. Most of plastic material is not detectable by a capacitive proximity sensor at a proper distance, sometimes becasue the density is low , sometimes because the plastic is too thin, for example, if you detect an empty 1mm thick plastic bottle, the detecting distance may be less than 2mm , if you fill the bottle with water ,then the detection distance could be longer than 5mm.
2. The Sensitivity, when the sensor cannot work, there is a sensitivity-adjustment screw on the back of the sensor, you can turn it clockwise with a flat head screwdriver to increase the sensitivity of the sensor
3. Load Current . High output current can result in prodct failue, Inductive load (for instance, motors which draw high current when started) is not allowed to be directly connected with this sensor, because this sensor can only provide 300mA current for the load , you can use this sensor to provide a low level signal for a PLC which requires very little current ,or you can control a small relay that requires a coil current less than 100mA.
Detecting Distance is adjustable. Turn clockwise to increase, counterclockwise to decrease. Range:1-10mm.
