| We are looking to use ultrasonic sensors for our 4th year design project, and was wondering if anyone could recommend some sensors for proximity detection, as large range as possible. Should we build our own Rx/Tx pair, or are there modules made for this purpose already?

Hi,
Try to find a pair in the robotics web site. They have them ready on a PCB with wires. Im sure you will find a supplier near to you...
Good lcuk.

| Robotics web site? Any links? Also, those are more short range... these will be mounted on a car, so something in the order of meters would be nice.

Check this ultrasound sensor from polaroid, it can meassure distance from 6 inches up to 35 feet. It comes with the signal conditioner board so you don't have to design and build it, you just have to make the program with the uC you are using or make a control circuit to command the sensor.
I think it costs less than 100 dollars, not sure really, check it on the internet.

There are some good sensors from Honeywell:

Remember that with ultrasonic you sense objects in a large range, compared to infrared in which you sense in one direction only.
I´m using sharp sensors for ranging, and you can use led+sensor for proximity, if you are on a budget.
Anyways, srf modules are good.
