From the shop's description

Adjustable, digital distance sensor with a cable length of 40 cm and nuts to facilitate mounting. Measuring range from 5 to 80 cm, is configured using a knob. Voltage supply 5 V. Description of Adjustable digital distance sensor E18-D80NK 5-80cm Adjustable, digital distance sensor with a cable length of 40 cm and nuts to facilitate mounting. Measuring range from 5 to 80 cm, is set using the knob located at the rearpart ofthe device – counterclockwise rotatingdecreases the range. Object detection is indicated through the occurrence of a low state at the output (black wire) and the switching on of the red led. The advantage of the sensor is also protection against reverse power connection. Connection Wire- brown – supply voltage – 5V Wire- blue – GND Wire- black – digital output – OUT there is no object – high state the object detection – low state The 5 V supply voltage and digital output make the sensor being able to be connected directly to the leads of the most available on the market of microcontrollers including AVR and STM32 and kits including Arduino. The product is compatible with Arduino For proper operation, it is sufficient to connect power of 5 Volts and the sensor’s output to any digital lead of Arduino. Reading works by causing a standard function digital Read(lead_number). Specification of adjustable digital distance sensor Supply voltage: 5 V Consumption of current: below 100 mA The measuring range is adjustable: from 5 to 80 cm Knob of range’s regulation – rotary potentiometer Output signal: digital (low state in the case of object detection, otherwise high) The led indicating the detection of the object Response time: below 2 MS Protection against reverse polarity Operating temperature: -25 °C to +55 °C Diameter: 18 mm Sensor length: 50 mm
