arduino pir sensor sensitivity

Unfortunately this PIR sensor is mislabeled (it looks like they swapped R9 R17). Under normal condition where there is no movement in front of the sensor, both the slots in the Sensor detect same amount of infrared radiation. The higher the potentiometer, the more sensitive the sensor will be. In this example an LED will light up when movement is detected. The actual sensor is inside a sealed metal can. Connect OUT to digital pin 2 on Arduino board. PIR Sensor Sensitivity Adjustment Variable Resistor: As it’s quite clear from its name sensitivity adjustment, this variable resistor is used to control the sensitivity of the PIR sensor. PIR sensor has three terminals - V cc, OUT and GND. The sensor in the PIR detects or “reads” infrared radiation “emitted” from objects all around us. You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor board. the one which is covered with a lens, consists of two slots and both these slots are made up of IR Sensitive materials. Determining R10 and R9 isnt too tough. The sensor in the figure above has two built-in potentiometers to adjust the delay time (the potentiometer at the left) and the sensitivity (the potentiometer at the right). Connect GND with GND on Arduino. The actual PIR Sensor i.e. If not properly adjusted it can create a problem due to which you will always get a high signal. There is a tiny window made of IR-transmissive material to allow the IR signals to reach the sensor. Detecting motion with the PIR motion sensor. Connect the sensor as follows − Connect the +V cc to +5v on Arduino board. For this example, you need the … You can trace the pins by looking at the BISS001 datasheet and figuring out what pins they are - R10 connects to pin 3 and R9 connects to pin 7. the capacitors are a little tougher to determine, but you can 'reverse engineer' them from timing the sensor and solving! The sensitivity potentiometer can’t really be quantified, but it reacts intuitively. The sensors sensitivity range between 6 to 7 meters (20 feet) and the detection angle is 110 degrees x 70 degrees. Adjust depending on your application. I have mine cranked to 11 ;-) Each object with a temperature above absolute zero (-273.15° Celsius, -459.67° Fahrenheit, or 0 Kelvin) will radiate infrared, even us humans, and even though we mere humans cannot see this. The can basically protects the sensor from noise, temperature and humidity.
