HC-89 Interrupt Sensor Module

Description

The HC-89 Interrupt Sensor, utilizing Hall Effect technology, excels in accurately measuring motor or wheel RPM. Its robust drive capacity exceeding 15mA ensures precise waveform representation and superior signal quality. The setup is straightforward with a fixed bolt hole, enabling easy installation.

The correlation photoelectric infrared count slot sensor module is a cost-effective, high-quality infrared counter module, compact in size and featuring an integrated LM393 chip. The module lights up a red LED with a low OUT pin when no object is detected and a green LED remains unlit with a high OUT pin when an object is present. It connects directly to a microcontroller, helping count the rotations of a smaller car using interruptions in the infrared beam.

Functionally, the sensor emits a square wave frequency corresponding to the object’s speed, achieved through essential components like infrared emitters, receivers, and an encoder wheel for accurate measurements. The module offers a TTL switch signal and analog outputs, simplifying microcontroller integration. This adaptability makes it a valuable tool for RPM detection in various applications.

The sensor features an output status indicator where lights turning off indicate a high-level output, while lights turning on signify a low-level output. It’s light-responsive, generating a high-level output when covered and a low-level output when exposed. Additionally, its direct compatibility with a micro-controller port makes it ideal for applications involving block detection sensors like motor encoders. The sensor supports versatile integration, allowing connections to relays, limit switches, and other functions. Furthermore, it can be paired with an active buzzer module to create alarms.
