Waterproof DS18B20 Sensor Kit


Image of Maxim Waterproof DS18B20 Sensor KitMaxim Integrated’s DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-wire bus that requires only one data line for communication with a central microprocessor. Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area.

DFRobot’s waterproof DS18B20 sensor kit includes a sealed temperature probe with a small terminal adapter board and digital sensor cable for their plug and play Gravity series for a complete solderless solution. While the sensor is good up to +125°C the cable is jacketed in PVC so they suggest keeping it under +100°C.

DFRobot’s Gravity series is an open-source, plug and play electronics toolkit. With dozens of standardized functional modules and powerful expansion boards, the Gravity series allows users of any skill level to easily connect, mix, and develop their own projects through a simple, color-coded, standard 0.1” (2.54 mm) pitch, three-pin connector ecosystem.
