Band pass filter?

Hi. I have an analog sensor that output voltage in a range of frequencies. I would like to creat a circuit to get the range of 0.5kHz to 1.2kHz and sendout const 5V if amplitude was over 3V.
This 5V I will connect to arduino digital input and send it as a tripped msg.
Any ideas?

I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system. So please, can we have a 'how to' step-by-step guide to OTA? Please? S.

I bought the Every because it implied it was backward compatible with the nano. No, it's not, as we found out. Be that as it may, any word on a getting the Every working with mySensors?

@Tmaster Never assume the original PCB was just a circuit of components, the PCB can incorporate RF shields and antenna radio ground planes...

Just wanted to say thanks for this, it is still relevant and useful six years later !

@eiten I haven't yet made any progress on finding a good VOC sensor, but along the way I did find out something interesting regarding CO2: namely, if you sleep with your bedroom door closed at night, then the odds are good that the CO2 levels rise to surprisingly high and unhealthy levels. The better CO2 sensors are factory calibrated and never again need recalibration for the life of the sensor (usually around 10 years or so), because they are used in HVAC systems to control fresh air intake to guarantee indoor air quality. As a for instance, here is one such CO2 sensor: https://www.digikey.com/en/products/detail/senseair/006-0-0008/15790694 At around $50 for just the sensor element itself, it's not exactly cheap, but then again, I'd say it's worth it, because who wants to be burdened by remembering to calibrate their CO2 sensors? Ideally, I'd like to find a sensitive VOC sensor that also will never require calibration. Nearly all, and maybe all, of the off-the-shelf IAQ montoring stuff that you might buy for, say, $300 or less seems to require periodic calibration. For that reason, this might be one of those occasions where build is rather than buy.

I am new in this forum and I have a question regarding mysensors and iobroker. I did not work with mysensors up to now. Since some weeks I use iobroker installed on a raspberrypi. Now I want to integrate my 433 Mhz doorbell in iobroker. I know, that there is an adapter for mysensors in iobroker. My question is: Is it possible to get a notification in iobroker if someone is pressing the button on my doorbell? As I understood, I have to connect the receiver to an arduino nano and connect the arduino to my rasberrypi on which iobroker is running.
