Hello - totally knew to this kind of work (15 year veteran C++ programmer electronics tech). What is the approx. transmission range of this IC with the D0420 RX chip? 5 feet? 20 feet? 50 feet? Does anyone know the approx. physical data range?
Thank you Walt
The following is from tests I performed with the Microchip rfPIC12F675 / rfRXD0420 system:
Distance Measurements for RF Transmitter/Receiver Sets
2 Mar 20041.. Using the 315MHz transmitter and receiver modules, the maximum, line-of-sight distance of separation for a valid response was measured at
190 Feet. 2.. Using the 433.92MHz transmitter and receiver modules, the maximum, line-of-sight distance of separation for a valid response was measured at 490 Feet. Notes: The approximate height of transmitter and receiver modules was 2 1/2' from the ground. This was using new batteries.I hope this helps.

Thank you so much for the reply - exactly what I wanted to see. Line of sight only - I assume then, that 50' (maximum for my purposes) with minor obstructions would work really well.

While I didn't document exact measurements made inside a building (an office/cubicle environment with partition obstructions), I did do some tests successfully.
I observed good results up to about 100' with the 433.92MHz set in going through several (> 4) layers of office partition.
