this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.
Hello,
I'm thinking about upgrading this board to include pinout for LIS3DH breakout board, like this one :
https://www.aliexpress.com/item/LIS3DH-Three-Converters-Motion-Accelerometer-Triaxial-Acceleration-Temperature-Sensor-Module-Development-Board-Replace-ADXL345/32840326778.html
and ditch the ADXL shield as it's not a good solution, it has either the ADXL345 which uses too much power, or the ADXL362 which is ultra low power but lacks advanced functionality like tap/double tap detection.
I would like to have feedback of users on this (do it sound useful ?), and also know if anyone uses the SMD footprints on the board, for leds and for reserve capacitors, as it could be a cleaner board without those footprints.
I would make the following changes :
put footprint for LIS3DH accelerometer along the "NModule connector" as it has too many pins to put elsewhere
keep only one I2C footprint on the side, for "GY-49" MAX44009 light sensor breakout board: https://www.aliexpress.com/item/GY-49-MAX44009-Ambient-Light-Sensor-Module-for-Arduino-with-4P-Pin-Header-Module/32828654450.html
temperature/humidity would be via the existing "SMD" footprint, it's not through hole but very easy to solder as it's 2.54mm pad spacing
remove SMD footprints for LED, add footprint for through hole reserve capacitor, keep SMD footprints for reserve capacitors only if I have space for them
shield would be a bit extended to go over the 2 M2 holes in the "power" part of the NModule, so it could be fitted with spacers and nylon screws and have stable/reliable mechanical connection between NModule and Shield. Basically this would be the footprint of the shield :
So in the end it would make one shield to have Temperature/Humidity/Light/Acceleration or Temperature/Humidity/Light/Door.
@bisschopsr said in BlackCircle Sensor - High "WAF" Temp/Hum. sensor:
Hi All,
Like the design thinking of this, although an older topic I did manage to get me one of these dishes. After taking it apart, I have one question that came to mind. Is the ventilation in the dish enough for the humity sensor? Is there any experience with that after running this sensor for a while?
Thx
Ralph
Hello, yes I think it's enough, in fact there's much more ventilation than in many commercial sensors which only have a small hole. But it's a good test to make, I'll try to compare to a sensor out of it's enclosure to see if there's significant difference or delay.
I didn't think the voltage drop would make enough of a difference to notice, but i guess it does. I might have to research and look for a more efficient Mosfet.
