That PIR module is a raw PIR sensor connected in a general purpose opamp circuit, provided by a LM324 series quad operational amplifier. One way of increasing the sensitivity is by changing the value of a resistor or capacitor in one of the opamp stages. This could lead to oversensitivity, and false positives. It depends on what values are used.

Adjust the sensor to point in the desired direction. Set the two adjustment controls on the underside of the unit (diagram C) to the following positions: TIME Fully anticlockwise DUSK Fully clockwise The unit will now operate during daytime as well as at night, illuminating the lamp for approx. 5 seconds each time. This allows testing to be carried out to establish the best position for ...
Arduino PIR Sensor Code, Sensitivity, Datasheet, and Range
20190806· PIR Sensor Timing ON period delay adjustment: This variable resistor is used to adjust the ON time when a human or animal is detected. This gives you the control to adjust the ON time after motion is detected by the PIR sensor. This function can help you in situations when you don’t want to use a microcontroller. This way you can turn on a relay for a few minutes which can be used to control ...
How do you adjust the time delay on a PIR sensor?
20200516· A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They do not detect or measure “heat”. The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR.
Overview | PIR Motion Sensor | Adafruit Learning System
20140128· You can adjust this if your PIR is too sensitive or not sensitive enough clockwise makes it more sensitive. Changing Pulse Time and Timeout Length There are two ''timeouts'' associated with the PIR sensor. One is the "Tx" timeout: how long the LED is lit after it detects movement this is easy to adjust on Adafruit PIR''s because there''s a potentiometer. The second is the "Ti" timeout which is ...
PIR Motion Sensor With Arduino in Tinkercad : 7 Steps ...
Some PIR motion sensors come with two adjustable potentiometers for changing the sensitivity and the duration of the activation signal. The PIR motion sensor here in Tinkercad Circuits does not simulate these adjustments. Optionally use a small screwdriver to adjust the sensitivity and time dials on the circuit board side of your PIR motion ...
How to Adjust the Sensor on an Outdoor Security Light ...
Some will have a sliding switch you can adjust to turn the sensor sensitivity up and down while others are controlled by a screw that you can turn with a screwdriver. Have someone else walk in front of the light while you are still on the ladder to test if the sensor is at the sensitivity you require. This is for motion sensors. For light sensors, wait for it to get dark. Adjust the sensor ...
