## Description

ELEGOO Ultrasonic Sensor, HC-SR04 Ultrasonic Distance Sensor Kits for Arduino UNO MEGA R3 Raspberry Pi,Datasheet Available to Download : desertcart.co.uk: Business, Industry & Science

Review: Great product - Good value for money, especially if you are a 'Prime' member!
Review: Great little ultrasonic distance measure sensors, they are 5v though! - These sensors are great for distance measuring with many small microcontroller projects. It's worth noting they require 5v (not 3.3v) therefore a bit trickier to use with the likes of ESP8266. It's worth noting it works intermittently with 3.3v but will be unreliable.

## Features

- Warning:Not suitable for children under 6 years. For use under adult supervision
- Warning:To be used under the direct supervision of an adult
- Ultrasonic HC-SR04 Distance Measuring Transducer Sensor Compatible with Arduino
- HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. When trigged it sends out a series of 40KHz ultrasonic pulses and receives echo from an object. The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse.
- Power supply: 5V DC; quiescent current: less than 2mA; effectual angle: less than 15°; distance: 3cm~450cm; resolution: 0.3 cm
- Package Content: 5pcs HC-SR04 with 10 pcs female to male dupont cable

## Questions & Answers

**Q: Does anyone know if this will work with apm2.8 flight controller?**
A: Apm 2.8 is arduino compatible you should have no problems.

**Q: Does this work with a micro:bit?**
A: Yes but you will need a separate power supply to power to sensor. Needs 5v but 4.5v should work.

**Q: is the sensor waterproof??**
A: Hi Georgina,
Thank you for your question. Sorry but those sensors are not waterproof. We hope this helps. If you need more information, please feel free to let us know.
Have a nice day!
Kind regards,
ELEGOOEU

**Q: I am looking to sense a movement of 1mm - is this switch that accurate?**
A: We could not achieve that accuracy, but it is very dependent on surfaces and surface angles.  We were trying to measure distances to people.

*by D***Y on 23 August 2017*

Works perfectly with a raspberry pi using python but you will have to accept the accuracy limitations which in my care is +/- 3cm's. Depending on the application you may also need a couple of resistors to limit the return voltage, plenty of online resources that explain what and how and cost less than 30p from Maplins.
