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.

Hello. Are these modules still in operation? As it is already an old project I would like to know the reliability and energy consumption? Thanks

@nagelc said in New Setup for Home Environment Monitoring – Using NRF24L01+, Arduino Pro Mini, and BME280: bme280 I read somewhere that the temperature sensor on the BME280 is sort of an afterthought. I did a few experiments comparing them to the DHT11/12/22 and found them only a little better. (Take this with a grain of salt, maybe you'll want to do you're own experiments.) I did do a lot of experiments with the DHT's and they really suck. +/-2°C Which turns out to mean +/-2°C offset (component variation) and +/-2°C measurement: +/-4°C from what the temperature actually is. My experience, yours may be better. Please post your experience with OTA. I haven't tried it on Arduino's but it's awesome on ESP8266. I hesitate with Arduino's because I had some erratic behaviour running Arduino's when pushing the memory limit. I, too, use the MQTT data transport to Home Assistant (HA) and I find that excellent. Getting data from HA is a bit tricky, but do-able. I have a flow meter and use HA to store the last read; meaning, if there is a power failure, HA sends the last read on Arduino boot. I don't use the EEPROM because that has a spec of 100,000 writes which the meter would do in about a year, thus, necessitating a new Arduino. I truly appreciate you sharing. Thanks! -OSD

I recently build successfully a mysensor node based on an Arduino Uno, a Robolink IR sensor and a Robolink DHT11 sensor. The last two from an Elektor sensor kit ever bought for my son when he was still interested by electronics . My controller is Home Assistant, so I did a merge of the given MySensors example sketch and the Home Assistant example sketch together with the DHT11 sketch. The airco is a Samsung one, so in the sketch you will find these defines uncommented. Replace by your airco manufacturer. People interested in building one, can find my sketch on https://github.com/ericvb/MySensorsArduinoSketches @ToniA a big thanks for the work to decode all these IR sequences!

Hi @talhatec , The remote controls work well. 4 months ago I installed a new battery and from time to time I press the button to check if they continue with battery, they sleep correctly. I remain pending to change the RF antenna for a better one and to improve some failures in the connectors of the battery that at the moment are very fragile (the pad has little copper). The casing can be purchased online https://www.ebay.com/itm/Bluetooth-4-0-GPS-Tracker-Locator-Smart-Alarm-Anti-lost-Device-Self-Portrait-SC/401394156488 For now the project is stopped, I want to test the Aqara sensors (I buy them this week), in any case the domotics is now my lowest priority.

@NeverDie Thx for appreciating the work done. There will also be an open source part in the future. When and how extensive the open source part will be, remains to be seen. The release of certain information (block diagram, ..., in this post) is related to those open source parts. There are some OBD solutions, however most of them (in my experience) give back low frequency data put by the car manufacturer on the OBD-bus (CAN, ...). Therefore transients evolving directly from the battery could only be recorded if the manufacturer sends those data accordingly on the bus. Due to the small bandwidth(also because of other car data that have to be sent, ...), such battery data are sent more often once per second or less. Fast battery events (i.e. cranking events, ...) are therefore imperceptible. Unless the manufacturer processes the fast events and then sends them (once per second or less), which is very unlikely if the manufacturer does not market this feature itself. Third parties devices for high frequency sensing costs several hundreds dollars. In my experience, important battery states (especially the fast ones) are recorded by measuring and processing corresponding data directly on the battery. I agree with you about the limits related to the communication over Bluetooth. But i think Bluetooth 5.0 will improve a lot. However, WiFi will always remain an important option due to the high data throughput. The combination of both (BLE & WiFi), especially with regard to energy consumption, will gain in importance.

@lis610 I have found with a 499K resistor the range is reduced to about 1.2m in a ABS box. With a 1Mohm it was about 3m, I do not have many high value SMD resistors to experiment with but the lower the value the lower the range. Just tried with a 333K and it operates about 0.8m in free air.

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.
