Hi there.
I am working on a project that would need a wireless communication between my house and a sensor station powered by a solar cell (using arduino Arduino). The range between these two is around 300m (1000ft). I already bought 2x nrf24l01 and I have tested the range but somehow i am getting only around 15m... Can someone give me advice on what method or product (that is not extremely expensive) i should use for this application?
Thanks!
Hi, I don't know this module but try to take a look at the datasheet here https://www.sparkfun.com/datasheets/Components/SMD/nRF24L01Pluss_Preliminary_Product_Specification_v1_0.pdf at page 25, are you sure that you are transmitting at full power?
However, I don't think that this kind of module can reach 300m, 0dB as max tx power and about -80dB as max sensitivity at the rx aren't very "high" specs.
In my last project I used a 433Mhz tx/rx module with 0/3dB as tx power and -115dB as rx sensitivity, I use it with a range of about 130m, (I don't know if it work with a distance greater than 130m).
https://hallard.me/nrf24l01-real-life-range-test/ looking here, seems that exist an improved version of your module with an external antenna.
On youtube I find this test for the "high power module" https://www.youtube.com/watch?v=lR60toEjHl8
So... first of all check your output power, if it doesn't work... you need a more powerful rx/tx module.
Hope this will help, bye.
Ps: search in other previous discussion, probably you will find useful information
