Ultrasonic Module HC-SR04 Arduino

Ultrasonic Module HC-SR04 Arduino
Ultrasonic Module HC-SR04 Arduino

The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object - just like bats or dolphins do.

This module offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect). Similar in performance to the SRF005 but with the low-price of a Sharp infrared sensor.

Perfect for collision avoidance on your next robotics or multirotor project!

Does it fit on the apm2.6 flight controller?

Hello, I noticed 4 wires in the sensos, but on the wiki page, other sonars are connected to output A0 using only 3 wires. So what wires should I use?
 Gerry01 4362 points
This verion has 4 wires: positive, ground, trigger, and eco. You power it up, feed a pulse on the trigger, an wait for a pulse in the eco pin. The eco width in microseconds is the time it took the audio to go to the object and come back. I didn't find specs about the 3 pin interface, but I think it will be the same, just need to use a 3-state output to do the trigger and read after that on the same pin.

Would it work good on a helicopter? I think i will detect te the ground on a landing

It will work, but not so good, as this one is a cheap sonar. Very precise sonar cost more.
 Gerry01 4362 points
It's precise within 2 or 3 cm, from 5 meter to 2 cm. Precition is better when you're reading closer to the object. If you can program the quad controller to take the reading of distance to floor at startup, and use that value as you reference for landing, it will work ok. Just remember that you need to filter out the readings, not with an average, but discarding values that are way off the last few readings.

I want to use an ultrasonic sensor to control the landing gear on my 800 hexacopter with Naza-M not KK2. Is it possible? and what do I need.
 Santhosh_r 331 points
Use a arduino to interrupt the signal to the landing gear and make the arduino read the signal from ultrasonic sensor and based on the distance actuate the landing gear

Clen pcb, clean soldering, not expansive at all. However, the value readings i have here ( maybe it is my program, don't know yet)are not enough stable to use it for on-board distance mesures, especially during obstacle avoidance calculations.
