This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface.

The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.

LM75A is a high-speed I2C interface, temperature sensor, in the temperature range -55 ℃ ~ + 125 ℃ The temperature was directly converted to digital signals, and to achieve the accuracy of 0.125 ℃. MCU can be read directly via I2C bus data in its internal registers, and through I2C to four data registers operates to set different operating modes.

LM75A has three selectable logic address pins, making it possible to simultaneously connect eight devices on the same bus without address conflict.
Module with temperature warning indicator.
