I'm trying to read sensor data from an MLX90614 using an ATtiny85 to turn on some LEDs if the temperature is in the corresponding temperature range. Right now, all my readings are under 0 degrees. I am very new to electronics so I suspect I am doing something wrong. I am using the Digistump Attiny…

Thanks for the help everyone. Inserting the wires directly into the temperature sensor module did the trick. It was a faulty connection between the module and standoff pins after all. Works both with and without the 4.7k pull up resistors. All in all: CHECK YOUR CONNECTIONS!!!

most likely the LEDS being driven with the SCL and SDA pins are an issue.
