Main Question or Discussion Point

Hello, I am going to interface wireless frequency meter transmitter with Arduino but before starting regarding sensor, I need to test the signal strength of this sensor (at different distances) by interfacing it with Arduino, I have never been used such kind of sensor before so any suggestion for testing the antenna strength will be a great help.

Welcome to the PF. :smile:

Can you post a link to the datasheet for this sensor? So far it's not clear what frequency range it senses, and how it picks up the signal. Thanks.

Okay, so it is a simple 2Hz-10kHz frequency counter that you interface with wirelessly. And you are wanting to do some experiments to see what the RF range can be (how far the sensor can be placed away from your PC and still communicate)?

They claim pretty impressive range numbers (from your first link):
  • 2 Mile Range with On-Board Antenna
  • Superior LOS Range of up to 28 miles with High-Gain Antennas
It looks like they are using the DigiMesh 2.4GHz protocol (I couldn't find the RF frequency in the docs you linked to, but I think DigiMesh is commonly used in the 2.4GHz band). Here are similar modules:

Look through your documentation for "RSSI" reading capability (received signal strength indication). That is the best way to see how strong your RF signal strength is as you vary distance and location (multipath interference will affect RSSI and generally will lower the effective range).
