New 4 ways infrared detection tracing sensors obstacle avoidance For Arduino car Description: This module is for intelligent car and robot automation machinery devices will provide a multipurpose infrared detection system solutions. Using infrared emitting and receiving tube division of components probe, and use LM339 voltage comparator (joined the hysteresis circuit more stable) as core components central control circuit. This system has many kinds of detecting function can greatly satisfy the guest all kinds of automation and intelligence of small the application of the system. Please pay attention to the friend, the tracing module just single limit comparator, no join hysteresis circuit. Single limit comparator, if the input signal Uin threshold in near the interference of tiny, the output voltage can produce corresponding vibration (ups and downs). In a circuit into positive feedback can overcome the shortcomings. We joined the hysteresis circuit, make working more stable. simple and easy to install, use 4-way independent work, work an unlimited number in the control panel with the probe separate installation location unrestricted module height
