OP, cool project. I have questions though:
How does the device detect very short bursts? After looking up the data sheet of the RF detector I believe you would need additional circuitry to not risk that very short bursts slip through the sampling of the ESP A/D input.
Second, the supply voltage of the detector seems to be 3.0 V to 5.5 V, https://www.analog.com/en/products/ad8317.html https://www.analog.com/en/products/ad8317.html
- RamboRogers 2y agoIt doesn't detect short burst well at all. It does detect traffic over a second or so, like a TCP session of an h264 stream. https://www.amazon.com/dp/B07FHZXTCZ?ref=ppx_yo2ov_dt_b_fed_asin_title https://www.amazon.com/dp/B07FHZXTCZ?ref=ppx_yo2ov_dt_b_fed_... Specifications: Working frequency: 1M--10000MHz Measurement power: -55dBm to -0dbm Output voltage: 0.33- -1.65V Detection slope: -22mv/dBm (typical value) Input impedance: 50Ω Supply voltage: 7-15V Size: as the picture Weight:7g
- 9dev 2y agoWhile researching for parts, I also found this one: https://www.amazon.com/dp/B07RR86PFC/ https://www.amazon.com/dp/B07RR86PFC/ It goes up to 10GHz, and it operates on 5V. Would that also be an option, and possibly allow to get rid of the boost converter too?
- RamboRogers 2y agoLooks cool! make one :-)
- slow_typist 2y agoThanks OP. The detector itself has a Pulse response time of 6 ns/10 ns (fall/rise) but of course the whole system will always be slower. 1 s is a lot though, got probably nothing to do with the sampling done by the esp.
