Description
Digital tachometer for rotational speed measurement with green LED CF5135C-Z
The digital tachometer LED CF5135C-Z with a clear green display is an advanced device for precise measurement of rotational speed. The reading is shown in revolutions per minute (RPM). The device uses an NPN Hall effect sensor that works with a magnet mounted on the rotating element under test. The module is ideal for monitoring shafts, fans, and other rotating mechanisms. The product is an excellent addition to automation systems and projects, including ESP8266, ESP32, Arduino, and Raspberry Pi.
Key technical features
Connecting the tachometer is straightforward and requires correct wiring of the sensor and power supply. The sensor has three wires: black (output signal), brown (power +), and blue (power -). The display module itself is powered via: red (+) and black (-) wires. To ensure correct and stable readings, pay special attention to proper magnet placement relative to the sensor. If there is no signal from the inductive sensor, the display shows LLLL.
