Random mini project from yesterday. I posted before about the outdoor temp sensor for my wireless thermometer, and how corroded it was. Something was wrong with the battery holder in the case, so I just pulled the metal bits out and soldered wires on, which I ran outside the case. So I got it back together but it still needed power.

I hooked it up to a couple AA nick metal hydride batteries, which of course are a little lower in voltage than alkaline primary cells (1.2 V for NiMH vs 1.5 V). The rechargeables work fine when charged, but the voltage dips down soon especially in cold weather. The transmitter seems to work okay down to around 2.6 V.

I took a solar panel from an old string of solar lights (water had gotten in and corroded the other guts), and hooked it in parallel, so I get some charging too. It's just connected with a diode, and should put out a few 10s of mA, which should be more than enough to compensate for the transmitter, which briefly draws about 7 mA for a second, every 30 seconds or so. I guess some kind of regulator would be good to avoid overcharging, but I'm going to try winging it.

I put it outside, and it seemed to survive another cold night. I put a meter across the battery today, when it's been around 20 degrees F and sunny, and saw the voltage was just under 3 V, which is good. I should find a slightly more permanent way to mount/shelter this, but for now the plastic container should work.

That temperature sensor on Google’s Pixel 8 Pro finally has a use

The Pixel 8 Pro is the first phone from Google to include a infrared temperature sensor embedded in the camera bar on the back of the phone. But when Google launched the phone in October the company didn’t really provide much of an explanation of what you were supposed to use it for.
Now we know: in addition to measuring the temperature of […]

It looks like the Pixel 8 Pro could have a temperature sensor when it launches later this fall, according to a leaked demo video that shows how it can be used to detect fevers when waved over your forehead. https://www.91mobiles.com/hub/exclusive-google-pixel-8-pro-leaked-video-design-built-in-thermometer/

I'm very pleased how well the #Dreame #robot vacuum cleaner works with #Valetudo after I have liberated it from the Xiaomi cloud. Even the integration with #Domoticz seems to be on a good way 🥰

So now I'm starting to look for an #AirPurifier, a #TemperatureSensor and a #HumiditySensor as well as valves for the #UnderFloorHeating that I can add and control without the respective proprietary cloud services 🤓

Any #recommendations? Ideally for fairly recent hardware? 🙄
