Description
Easy to use temperature sensor for Arduino. it is powered by 1.4 V to 3.6 V. It communicates via the I2C bus, it has built-in pull-up resistors of 4.7 k Ω . The sensor measures the temperature with an accuracy of up to 0.5 °C with a resolution of 0.0625 °C.
|
The product is compatible with Arduino The manufacturer providessample codealong with the connection scheme for users ofArduino. |
Due to the fact that the maximum voltage with which the system works, is 3.4 V, to work with Arduino, necessary is a voltage converter. The exceptions are the modules operating with the voltages of 3.3 V, for example,Arduino Pro Mini 328 - 3.3 V/8 MHz.
