https://devzone.nordicsemi.com/f/nordic-q-a/55338/engine-noise-concernsHello, I&#39;m working on a project that contains 2 small enclosures each with a sRF905 and processor that monitors temp and humidity. One of the enclosures is mounted in the engine compartment. Each enclosure then (&amp; currently on a prototype) transmits iten-USTelligent Community 13Mon, 09 Dec 2019 12:10:11 GMThttps://devzone.nordicsemi.com/thread/224407?ContentTypeID=1Mon, 09 Dec 2019 12:10:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b2f1496-f258-4fe7-9285-b5b6df50b6f8bjorn-spockeli<p>HI Dan,&nbsp;</p> <p>Is the truck engine a combustion engine or an electrical motor? If its the first then I would not expect a combustion engine to emit any RF signal that would interfere with the nRF905 transmission/reception. If its an electrical motor, then there could be an issue and I would recommend doing a measurement with a spectrum analyzer to see if the engine is emitting any noise in the 900Mhz band.&nbsp;</p> <p>Best regards</p> <p>Bjørn&nbsp;</p><div style="clear:both;"></div>
