Which presentation to use for a Turbidity Sensor?

Shiny Hardware Contributor last edited by

I'm using this analog sensor: https://www.dfrobot.com/product-1394.html

and I saw there's a S_WATER_QUALITY
but I'm not sure what V_ to use.

The sensor basically measures how transparent the liquid is, to detect if gunk is growing in your water tank or pipe.

@Dwalt Thank you very much, now I understand better why the measurement of the voltage on input A0 was never good ..

@scurb This looks very interesting and my factor now to save me from having to create my own :-). I have been planning to do the same thing (although maybe on a smaller software scale) by writing a simple Python server that would pull serial packets off of a gateway arduino (either running mysensors or something I write myself) and pipe this through MQTT to openHAB. I have two questions: How do you interface with a sensor network? Do you go through a serial connection to read the serial packet format (a,b,c,d)? I see several implementations that put the mqtt client directly on the Arduino, but it seems much cheaper for me to just plug it into a USB port to get a virtual serial port instead of investing in a separate ethernet shield How does an item configurations look like for a switch in openHAB? I'm looking to build a toggle switch which toggles light on or off every time it is activated, and I cannot really understand how to configure the switch to allow this behaviour for an mqtt input. Feel free to take the second question with me directly since this might not be very interesting to the others in the forum

I'll update the PDF once I get to my own computer (which should be Sunday evening)

@andreas-sieber The white circle on the PCB you mean? IMO That's silkscreen indicating the touch area.

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.

Oh, I never even thought of that as a possibility. I really like KiCad, and it's my preference. For a while I had Eagle for work, but even then I still preferred KiCad whenever I was given a choice.
