This digital temperature sensor allows for easy mounting on a heating surface via an M5 stud screw and nut.
The sensor itself is made using a solid aluminium board. Heat compound paste can be applied to the back of the sensor for better heat conductivity between the sensor and your heating area.
This sensor provides a 12 bits temperature reading from -55°C to 125°C with a resolution down to 0.0625°C.
Digital connection and does not require any additional analogue electronic circuits

Note: Please note that the default I2C address for this sensor is 0x4F (with address pins ADD1 = floating, ADD0 = floating). For any other address, you can solder jumper J1, J2, J3, J4. Check out the datasheet for the 8 select-able I2C addresses.
J1 – connects 5V to ADD0
J2 – connects Gnd to ADD0
J3 – connects 5V to ADD1
J4 – connects Gnd to ADD1
