Detecting the distance to an object with an ultransonic sensor
With the capture capability of Netzer a simple ultrasonic sensor like the HC-SR04 module can be used.
For that reason the sensor shall be connected like:
| Sensor signal | Netzer signal | Further descriptions |
|---|---|---|
| VCC | - | Connect the sensor to +5V |
| GND | GND | Ground signal |
| TRIG (I) | IO3 | The trigger signal |
| ECHO (O) | IO0, SPI_INT | The echo signal. Due to the Netzer pins are +5V tolerant, no voltage divider is needed! |
