nRF24L01- Health concerns

[Astalor]

Hi,

nRF24L01 seems like a perfect choice for home automation project that I have in mind .. I will have to install about 20 of those around the house.

My question is - do they transmit anything when there is no data to be transmitted ? Are they listening completly passive for a signal ?

Hello Astalor

Figure 11, page 37 of the nRF24L01P product specification shows receiver operation. Either as long as it receives no valid data packets, No_ACK is set, and it has no response payload, the chip will only passively listen, and not transmit anything.

Also, assuming that the question was if there are health concerns over 20 transmitters in a house, then this would be covered by the SAR compliance for the product in question. The nRF24L01 is a 0dBm device which is below the 5mm limit for most, if not all, regulatory bodies.
