As I ordered the sensor I was a little disappointed because it was not working as I expected, After contacting the seller it was very fast clear, I had the wrong power supply, 1.5V instead of >4V Now it is working like a charm with 3 AA alkaline and it is sending data every 10 minutes to Domoticz. Overall, very satisfied, going to order more.
Simple accurate digital temperature measurement to 1/16th Deg C. These can pin for pin very simply interface directly to Raspberry Pi GPIO and Picaxe microcontrollers using internal WPU Weak Pull Up from software by activating internal WPU OR by more conventional external 4k7 resistor. ~ Andrew
