Wireless Sensor Tunnel Railing Circuit Infrared Height Limit Detection Application Training Kit

Application In today s increasingly busy traffic cars often pass through tunnels and culverts Many vehicles often load at a super high height and they do not pay attention to traffic signs when they are fatigued resulting in traffic accidents that injure people vehicles tunnels and culverts At present mostly wooden or metal sign poles are used as warning tools But if it is super high there will still be accidents that injure people or injure the car For this reason it is proposed to use infrared wireless sensing tunnel railings Once the car exceeds the height the two methods of sound and light will be used to alarm in front of the car to avoid accidents Debugging Steps ① Debug the power supply part mainly to measure whether the output voltage of the power supply is correct If the integrated circuit is installed on the socket of the integrated circuit it is not necessary to plug in the integrated circuit when debugging the power supply After confirming that the power supply is in good condition plug in the integrated circuit the power supply should be disconnected at this time Use the 3 pin output voltage of the multimeter 7805 which is normally 5V and adjust the voltage to the required value of the circuit 5V ②Aim at the infrared transmitting and receiving tubes adjust the potentiometer Rp2 and make the output pin of LM567 output low level If you can t make LM567 output low level check whether the components of the circuit are installed incorrectly
