PIR motion sensor and TM1637 counter with Arduino NANO to count the number of movements
Here, we will see the circuit to interface a PIR motion sensor to an Arduino NANO along with a 4 digit counter named TM1637. This circuit will help you to count the motion of people in a given area and we could see the number of movements in the counter module.
Purchase the module from this purchase link. When somebody moves in front of the sensor, movement will be counted and will be displayed on the counter.
