🌡️ Enhanced DS18B20 Temperature Sensor Module: Ideal for Arduino and Raspberry Pi Projects Review

I use this to control the air temperature for my telescope focus dial. One downside is the annoyingly bright blue LED, but duct tape solves that problem.

Don't forget the resistors, you'll need them. But other than that, it connected in minutes and is incredibly accurate. Analogue or digital. A wire for Pi. Simple as can be.

Works great! No complaints! By connecting it to my Raspberry Pi, I get reliable temperature readings. The only odd thing is that I somehow get a reverse voltage across the HDMI cable even when no other power supply is connected to the Pi, causing the LED on the small circuit board to light up. Although it doesn't seem to be a problem.
