Product Details - Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc. The PIR Sensor module allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor's range. It is often referred to used "PIR", "Pyroelectric", "Passive Infrared" and "IR Motion" sensor. The module has an on-board pyroelectric sensor, conditioning circuitry and a domb shaped Fresnel lens. 100% Brand New and High Quality Color: White + Green Infrared Sensor with Control Circuit Board The Sensitivity and Holding Time Can be Adjusted Working Voltage Range: DC 4.5V- 20V Current Drain: <60uA Detection Range: <140° Voltage Output: High/Low level Signal: 3.3V TTL output Detection Distance: 3 to 7m (can be adjusted) Delay Time: 5 to 200s (Can be Adjusted, Default 5s +/- 3%) Blockade time: 2.5s (Default) Trigger: L: Non-repeatable trigger H: Repeat Trigger (Default) Work temperature: -20-+80°C Trigger Method: L Unrepeatable Trigger / H Repeatable Trigger Material: Mixed Material Dimension: 3.2cm x 2.4cm x 1.8cm (Approx) Sensitive Setting: Turn to Right, Distance Increases (About 7M); Turn to Left, Distance Reduce (About 3M) Time Setting: Turn to Right, Time Increases (About 300S); Turn to Left, Time Reduce (About 5S).
