RF proximity Project

Wireless & IoT

Hi everyone,

i would like to know what are available components for my project? i need RF sensors that will detect two objects that they are 1 meter (or can be calibrated up to 3 meters) apart from each other.

thank you.

First you will need an Arduino board, sensor, and RF transmitter. Then your receiver will require an Arduino board, an RF receiver, a logic level converter, and a Raspberry Pi.

There are no “RF sensors” than can be used to measure distance between objects.

I will look into this. thanks.

So I bought a proximity sensor and it creates the signal when there is nothing in front of it. I need the opposite I need the signal to come when something comes in front of it. What do I need to buy? This is what I bought https://www.amazon.com/gp/aw/d/B005GNPR … =306936011
