The sensor can detect objects at a distance of from 10 to 80 cm. The output is an analog signal whose value depends on the distance between the detected object and the sensor. The closer object is, the voltage at the output is higher.
The measuring sequence after connecting the power.
These sensors are readily used by designers of mobile robots e.g. in fighting constructions, to detect the enemy or chassis platforms, where it is used for obstacle detection.
The product is compatible with Arduino
The sensor output should be connected to any analog lead, the measurement is output using the function analogRead(sensorPin);. The sample project with code can be found on the bildr website and in our guide.
The sensor has three leads: power - Vcc (voltage from 4.5 to 5.5 V), weight - GND and analog output signal Vo, the value of which depends on the distance between the sensors and the detected object, this dependence is presented on the chart. The following figure shows the location of the leads.
