In this Raspberry Pi distance sensor tutorial, we will be utilizing the HC-SR04 Ultrasonic Sensor with our Raspberry Pi. This guide will go through showing you how to wire up the sensor with the Raspberry Pi as well as exploring how we can utilize the sensor also to read distance I've given this a code a good go and got it working to a point. The first section of the code is for the distance sensor and seems to work fine, also the 'if' statement, when I get it to check the distance between 2cm and 30cm also seems to work fine by switching on a relay for 5 seconds, but what I would now like to do is have it switch on 2 relays for 5 seconds, not just the 1, but not sure how to add the second relay into the mix. Currently I have the Pi connected to a 4 relay board Ultrasonic sensor with Raspberry Pi, Overview: Ultrasonic sensors can measure distances using sound waves. The type of Ultrasonic Sensor I will be using with the Raspberry Pi is the HCSR04 which is the most popular one

Here we begin the setup process of the ultrasonic sensor. Some knowledge of how to set up a Raspberry Pi and run Python code is assumed. HC-SR04 Connection Raspberry Pi and Ultrasonic Distance Sensor Circuit Illustration. I set up the circuit on a breadboard which made it easier to connect a resistor voltage divider. You can plug the SH-SR04 sensor into the breadboard directly or by attaching a ribbon cable. Additionally, I use a T-Cobbler that allows me to connect the Raspberry Pi GPIO pins. The distance sensor has only three connections: red (5V), black (GND) and yellow, which is the data pin and connected to the MCP3008 ADC. For some, the alarm bells may sound and ask why a 5V module is connected directly, although the Pi's SPI bus should not receive more than 3.3V input Distance Calculation Python Code GPIO.output (GPIO_TRIG, GPIO.LOW) Time.sleep (2) As mentioned in the datasheet of this ultrasonic sensor we are using the above line of code to make the GPIO pin low for 2 milliseconds. Time.sleep (2) - This line of code introduces the delay in the process If you prefer the Pi, then you can also set up the HC-SR04 to work with the Raspberry Pi.

Here is a summary of all the components you will need for this project How to Measure Distance with Raspberry Pi You can measure distance using the HC-SR04 ultrasonic sensor with Raspberry Pi. The HC-SR04 sensor can measure distance from 2mm (.02m) to 400cm (4m). It sends 8 burst of 40KHz signals and then waits for it to hit an object and get reflected back Our HC-SR04 sensor is connected to our Raspberry Pi! Sensing with Python. Now that we've hooked our Ultrasonic Sensor up to our Pi, we need to program a Python script to detect distance! The Ultrasonic sensor output (ECHO) will always output low (0V) unless it's been triggered in which case it will output 5V (3.3V with our voltage divider!). We therefore need to set one GPIO pin as an output, to trigger the sensor, and one as an input to detect the ECHO voltage change In this Raspberry Pi tutorial, we're going to introduce a new sensor, the HC-SR04 ultrasonic distance sensor, along with handling GPIO input.The HC-SR04 dist...

Raspberry Pi library for the VL6180 i2c distance sensor - leachj/vl6180_p An ultrasonic distance sensor has four pins: Gnd (ground), Trig (trigger), Echo (echo), and Vcc (power). To use the sensor, you need to connect its Gnd pin to a GND (ground) pin on the Raspberry Pi, the Trig pin to a GPIO pin on the Pi, and the Vcc pin to the 5V pin on the Pi. The Echo pin is a little more complicated My experience with this sensor is that the code gives differing results depending on the current CPU load on the Pi. See post 50 at the above website. I ended up doing 3 samples each time and keeping the lowest result. The minimum time between good readings is about 2 seconds — not useful. Too bad there doesn't seem to be a way to sleep until the ECHO pin causes an interrupt. This.
