DIYables DS18B20 One Wire Temperature Sensor for Arduino, ESP32, ESP8266, Raspberry Pi
Click to zoom
Quick Overview
This DIYables DS18B20 temperature sensor set includes five waterproof one-wire digital temperature sensors with stainless steel probes and five 4.7kΩ pull-up resistors. Each sensor features a 1-meter cable and provides accurate temperature readings from -55°C to +125°C, making them ideal for indoor and outdoor temperature monitoring projects.
The DS18B20 uses the Dallas 1-Wire protocol, allowing multiple sensors to share a single microcontroller pin with unique addressing. The waterproof stainless steel probe design enables reliable measurements in wet environments, aquariums, soil monitoring, HVAC systems, and weather stations.
Compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and any 3.3V or 5V microcontroller, these sensors work seamlessly with popular libraries like OneWire and DallasTemperature for easy integration into IoT and automation projects.
