Descrição

Description: This module for intelligent vehicle, robots and other automated mechanical device to provide a versatile infrared detection system solutions.The use of infrared transmitting and receiving tube equant Tatemoto devices composed of probe, and use the LM339 voltage comparator (joined the hysteresis circuit more stable) as the core components of control circuit.This system has multiple detecting functions can greatly satisfy customers various automation, intelligent small system application. Please note, the current tracing module is a single limit comparator, did not join the hysteresis circuit.Single limit comparator, if the input signal Uin in threshold value near the disturbance, the output voltage will produce corresponding jitter (UPS).In the circuit into the positive feedback can overcome this shortcoming.We joined the hysteresis circuit, making the work more stable. Feature Four way infrared detection tracing photoelectric sensor smart car tracking module of black and white line identification Easy to install, easy to use4 way work independently, work is not affected by limiting the number of  In the control board and the probe is separated from, the installation location restrictions Specifications: 1 .Operating voltage : DC 3 .3V-5V 2 .Current: try to choose more than 1A power supply 3 .Working temperature: -10-+50 4.Install Aperture : M3 screws 5.Detection distance : 1mm to 60 CM adjustable, the closer the more stable performance , white reflective distances . 6.Size : 42mm in the control panel×38mm× 12mm (length× W×High) Small plate forward 25mm×12mm× 12mm (length× W×High) 7 .Output Interface : 6 -wire interface ( 1234 4 -way signal output, + positive power – power that is negative ground ) 8.Output signal : TTL level ( can be directly connected microcontroller I / # 0 , is reflected back to the sensor sensing infrared light , the red light is on, the output low ; when no infrared light , the light is not lit , the output high . ) Applications: 1.Smart car or robot hunt ( including black and white lines ), walk along the black line path , also known as tracing . 2 .Smart car to avoid the cliff , anti- fall . car to avoid obstacles Shipping list : A tracking module as shown in Figure 1 set (hollow board a small plate forward 4 + ) 2 20cm long DuPont line 12 , to facilitate wiring
