The DS18B20 is a robust, digital temperature sensor providing 9 to 12-bit Celsius measurements across a -55°C ~ 125°Crange with±0.5∘C accuracy. It uses a unique 1-Wire interface requiring only one data pin for communication, allowing multiple sensors to operate on the same bus.
Waterproof digital temperature sensor DS18B20 with adapter module
Pull-up resistor included on the adapter module, connect directly to you microcontroller
DS18B20 Temperature Sensor works with Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V or 3.3V microcontroller.
Measure the temperature directly in places like water or soil
Stainless steel encapsulated waterproof temperature sensor DS18b20 temperature sensor 18B20.
The 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 by definition requires only one data line (and ground) for communication with a central microprocessor.
It has an operating temperature range of -55°C to 125°C and is accurate to ±0.5°C over the range of -10°C to 85°C.
The DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. (But this version no support the parasite power, please note that).
