I have already set up an ultrasonic range finder using the basic HC-SR04 proximity sensor but am in need of another prototype
I now have a 2 pin enclosed transducer SMATR10H40X80 but I do not know how to set it up or change my existing code. I am using an UNO board and basic breadboard equipment. Below is basic manufacturers information.
All help or information is greatly appreciated and thank you in advance.
What do you want to do with the transducer?
I would like to measure an object that is between 12 and 36 inches from the sensor and do so wirelessly.
For now I only need to know how to set up the 2 pin transducer, the connectivity will come later.
That is only a sender/receiver. You will need additional circuitry to make it into a rangefinder (transmitter drive signal, gain for echo detect, etc.).
I apologize for my ignorance but I was under the impression that my 2 pin sensor had that same functionality as the HC-SR04 sensor.... the ability to transmit an ultrasonic signal as well as receive the echo information.
If this is not the case, what other specific materials might be in need of?
Why not just use the HC-SR04 rangefinder? It is not a trivial task to build a rangefinder from the part you have. The transmit drive can be done with a digital out put and transistor, but to receive the echo requires an amplifier (usually with automatic gain control).
I want it to be used wirelessly outdoors where it will be exposed to the elements.
The HC-SR04 will not be suitable due to its open face design that will allow rain water and dust to enter the housing itself.
Agreed, the sensor by itself is almost useless with an Arduino. You can buy ultrasonic ranging modules that are intended to be used outdoors. A backup alarm for an automobile is one example.
How do you imagine the sensor to be used "wirelessly"?
Ah, I see. Google "diy ultrasonic rangefinders". There are several that show what is involved. A Sensitive DIY Ultrasonic Range Sensor – Kerry D. Wong for instance. Compare the specs of the transducer they used to yours, You might be able to just copy one of their designs.
But I agree with jremington as it is almost sure to cost more to build it yourself.
I intend on using battery power with possible solar backup to run the sensor, incorporating the NRF24L01 2.4 GHz RF Transceiver to transmit the data via wifi.
This will all be inside a "weatherproof" housing, similar to the shape and look of a hockey puck. I intended on flush mounting my existing sensor with the top of the housing so that the housing itself would not interfere with the signal transmission.
Thank you your help so far.
That is a challenging project! The transducer that you linked will indeed need additional circuitry such as described in the link posted by groundfungus. Or, you could modify an existing auto backup alarm for use with the Arduino.
The NRF24L01 radio will not communicate with existing wifi installations but there are plenty of examples of its use to transmit data to a homemade base station. For use with an existing wifi network, you can use a wifi module such as that described here: The finished Arduino wireless water sensor | Lifeboat Farm
Tell me about it haha. Thanks for the links and help.
I will look into the new circuitry and see what I might need.
I may also look into somehow making the original PING sensor weatherproof.
Does anyone know about the circuitry that I will be needing to operate the sensors?
