The temperature sensor uses a thermistor which returns the ambient temperature in the form of a resistance value, which is then used to alter Vcc (5V with our Seeeduinos). Our board then converts this voltage value measured by an analog input pin to a temperature. The operating range is -40 to 125°C , with an accuracy of 1.5°C .
