Hi Duncan I wonder if you can help me. I have an outdoor weather station with an inbuilt temp/humidity sensor that went off line a while ago. Other parts of the weather report ok to the console like wind speed and direction etc. The original temp/humid sensor looked like it had corrosion on it so attempted replacement. The sensor pcb had part number EW105DV1. I replaced it with an AHT10 temp/humid sensor. Both have connections for Vin, GND, SCL, SDA which I think I connected right, but still getting temp and humidity from my outdoor weather station as off line. Other units are ok. Any ideas? Are these sensors compatible? Thanks mate.
Hi Rob There is certainly going to be an issue with the IIC addressing and registers being different between the two sensors. My guess it that the station is going to need the original sensor installed to get it working again. Best regards, Duncan
@@Uncle-Duncan-Shack Thanks for the quick reply mate. I only changed it because the original went off line, and on inspection looked corroded. When you say original sensor, do you mean one exactly the same?
I've tried to explain this to EV lovers. Ships are vastly more efficient than cars and trucks, yet there are no electric powered ships crossing the Pacific, or even moving from the Persian Gulf to Europe. If EVs were the least bit decent, they should all be electric, all the shipping. And none of it is. Maybe there's a handful of ferries across the globe, but if electricity is a decent replacement for fossil fuels in cars and trucks, the oceans should be covered in electric cargo ships.
The problem is batteries, and the amount of energy storage a battery has for its mass. Since we're only driving a car 200-300 miles before recharging it, we need hella less battery mass than if we're running it across the Pacific. PLEASE stop comparing Kumquats to Supernovas.
@@Uncle-Duncan-Shack Which is why it works for cars and not for ships. Also, let's ponder one day on how many ships and trains are actually Diesel-Electric Hybrids, and why.
Hi Glyn, Thanks for commenting. It was an interesting and fun video to make as this information is easy to research. This is nice to see it all in perspective. Duncan
Hi Nick Yeah, it feels very wrong not wearing a safety belt. The ride is quite an experience, I love old cars. Thanks for looking and commenting, good to have you here!
I opened it up and found the wires attached to the sensor have been disconnected. The soldering must have come off and also there was some brown stuff over it im assuming rust. I cleaned that up but now i dont know which side the green and red so onto the sensor bulb as it doesnt indicate
Hi Nick, all the best for 2023 to you too. Thanks for watching and commenting. This cooler is life saver in hot weather and times when I have to run stuff of an inverter as it only draws 35 Watts.
I did the police lights program with fully addressable led strip on Arduino and it was amazing. Once I did that it was game on for adjusting the program and creating anything I could dream up. The program I had used hexadecimal for the color brightness and time. 😊
My biggest problem with these kits are I forget that they are not heavy duty,but for the price not a mayor issue. It is good to have the right tool for the job. Thank you for sharing. 👍
@@Uncle-Duncan-Shack nope uncle D, I do watch the engineering mindset, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xwvkojKiLJM.htmlsi=Rgyh8fl631SuQ2PX
