I have some problems with this sensor. I have connected it via I²C, address 0x01. Calibration runs fine with a difference of ~12 Hz to the target frequency of 500 khz. But the problem is - it is receiving absolutely nothing. No disturbers, no lightnings so far. In my opinion, wiring and chip (i use a "selfmade-board") must be ok, because otherwise calibration would fail. Why it is not providing interrupts? There must be always "something in the air", right? I have tested it with my Arduino MEGA and with my Raspberry Pi. Any clue what i can try now?
This is similar to my experience with the chip. Although I do get disturbers, I very rarely get strikes for even strong lightning that shakes my windows. Have you adjusted any of the registers? Do you live inside a metal house or one with a metal roof? Have you tried it outside? Have you tried to create a disturber by sparking two AA batteries close to it?
Hello, Yes - i think i have tried almost everything possible. I have generated sparks with the spark source of a lighter.
Now I've switched to SPI communication to try another library for arduino. Calibration works fine, but this time I have always the "too much noise" interrupt. Played around with the registers - no chance. OK, maybe it's right - I have a lot of stuff near the computer, like telephone and WiFi router, but they use much higher frequencies. I will try it outside with my notebook soon.
Although a different antenna might have been a better choice, this chip is designed for an LRC antenna with a natural frequency of 500kHz. 500kHz was a good choice as it is an unused part of the spectrum and one where lightning shows up very bright. Changing to a different antenna would not be a possibility.
Yes there has. Had three storm fronts roll through yesterday. Strikes close enough to rattle one's teeth.
Seriously, if you want a beta tester, I am your man. I have been working on a lightning detector for 3 years now. When the AS3935 came out, I thought my life would get easier, but with the bug on the chip, its been a pain in the but.
Please make sure you can switch between SPI and I2C interfaces and that you can adjust the I2C address. The chip has a bug that makes it difficult to use I2C at the address of 0. You can read my website for more info.
