SEN0547 Waterproof Digital Thermal Probe LM35DZ Module For Arduino

These are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling.

Specifications:

Operating voltage 4.0V ~ 20V
Temperature range 0 ~ +100
Power single 5V supply, 0 when the output is 0 V, and is increased by 1, the output voltage increases 10 mV.
Output leads: Red (VCC), yellow (DATA), black (GND)
Stainless steel housing (6 * 50mm), lead length 100cm

Note: Operating voltage 4 ~ 30V, the current drawn from the power chip is almost constant (about 50A), so that the chip itself has almost no issues with heat dissipation. Using such a small current draw also makes this chip is particularly suitable for battery powered applications, the output can be removed by the third pin, no need for calibration.
