Moving Sensor / Detector Schematic Diagram using IC NE555 and Phototransistor L14F

Robometricschool. - One of the sensor or detector that very useful in security electronic system is moving sensor detector. With this sensor we can sense something that usually move in our field as like human, animals and others. So we can detected this movement and we can do something if it will dangerous in our live.

In here we will give you simple electronic circuit schematic moving sensor / detector using IC NE555 and Phototransistor L14F as like in Figure 1 below:

Electronic Schematic Diagram

Figure 1. Moving Sensor / Detector Schematic Diagram using IC NE555 and Phototransistor L14F

Component List

You can see more all components that used in Moving Sensor / Detector Schematic Diagram using IC NE555 and Phototransistor L14F. Main component in this circuit is IC NE555, Led IR, Phototransistor L14F and IC LM1458.
 
Schematic Performance

Moving sensor / detector schematic diagram divided into two parts, there are transmitter and receiver. Transmitter part is the part that will send infra red data using IC NE555 and LED infra red. And in receiver part using photo-transistor L14F that will receive IR signal from LED IR in transmitter. Signal from photo-transistor will allowed through to IC LM1458 as signal conditioner. 

IC1 (NE 555) is an astable multivibrator which connect with IR LEDs produce infrared rays 5Khz. infrared rays will be received by the photo transistor Q1, if under normal conditions the output pin (7) of IC2 will be low (low). and if you are moving objects between the transmitter and the receiver on pin 7 of the IC 2 will be conditioned (high). bazzer bell circuit or can be connected to the output of IC 2 is to demonstrate the existence of this disorder. As note that POT R5 can be used for sensitivity adjustment
