RhydoLabz "ECHO –PRO, 5in 1" Ultrasonic Distance Sensor is an amazing product that provides very short to long-range detection and ranging with a resolution of 1mm. The ECHO-PRO is a 5 in 1 sensor module which output the distance data as Serial ASCII, Pulse width and Analog output. The module has an onboard temperature sensor which outputs the ambient temperature via Serial ASCII. Apart from this the module is also equipped with Proximity sensing output, which will generate a high going signal if any object comes under the presented distance range (2-500cm).The ECHO-PRO can operate in "AUTO" mode as well as "Manual" mode. In "Auto" mode the module automatically send the ultrasonic signal and do the measurement and give the distance output, whereas "Manual" mode requires external triggering pulsate to start the measurement.
Since there are various interfacing options (ASCII, PWM and ANALOG) available on the module as a standard, it will be easy for a developer to select the optimum one based on the resources available on the microcontroller. No need to buy and stock different modules.

Pinout Diagram:


Pin Description:

  • Output: Serial ASCII, Pulse width, Analog, Temperature Output, Proximity       Detector

I was hesitant to place an order, mainly because many other cheap sensors were available in market. Finally considering the boasted spec I placed an order. Next time I wont hesitate on placing an order with rhydolabz! Its worth the price! :)

    • Q
    • Is this module can measure a value like 5.1, 10.6cm. with an accuracy of 1mm

      asked by Niju K Jacob on January 14, 2019
    • A
    • Under standard operating condition at our lab. we could achieve the resolution of 1mm, but unable to give assurance on that as the resolution depends on several factors including wind.

      If your design required such a high resolution, it is better to select laser based distance sensors.

    • Q
    • Sir/Madam
      1) It seems the PCB/ electronic components are exposed to humid ambient. Will thePCB and components withstand the ambient humid conditions?
      2) Is there a mounting accessory for the PCB available?
      3) What is the full time period of the PWM pulse for the 500 cm?
      4) Is the PWM is open collector output or TTL output?
      5) Kindly send me the data sheet of the ECHO-PRO through mail.

    • 1) Yes, if you are using it without enclosure in very very humid (out door) condition , it will effect the reliability as well as accuracy. For normal ambient condition, the module works reliably. You can enclose it in a suitable container.
      2) No , you have to mount it as per your end use.
      3) As mentioned in product feature, the module output the data on every 100ms , and the time period will be same.
      4) It is normal TTL output .
      5) Please refer the wiki pages mentioned in the product page.
