4Pcs DS18B20 Temperature Sensor 1 M, Waterproof Digital DS18B20 Sensors, DS18B20 Temperature Probe, Stainless Steel Probe Compatible for Arduino/Raspberry Pi/ESP32, ESP8266,
Package Quantity:4 Pcs DS18B20 Temperature Sensor Waterproof, Stainless Steel Digital Probe 1M Cable.
Operating Voltage: 3.0V–5.5V ( Compatible Arduino/Raspberry Pi /ESP32, ESP8266 ), Temperature Range: -55°C to +125°C (±0.5°C accuracy between -10°C~85°C), High-temperature resistant cable (-55°C~125°C) with anti-kink design.
Plug-and-Play: 1-Wire bus protocol supports multi-sensor parallel connection with a single data line. TIP: Black lead goes to ground. Red lead goes to 3.3vdc and yellow is your data line.
Usage Notes: Wiring-Requires 4.7KΩ pull-up resistor (some boards have built-in support); Only the probe is waterproof; cable joints need insulation.
Wide Application:Process temperature monitoring /Air conditioning monitoring /Hatching temperature control / Temperature measurement of aquaculture /Temperature monitoring in greenhouse /domestic refrigerator /Cold storage temperature monitoring /Telecommunication room monitoring/ Warehouse temperature monitoring/ environmental monitoring, etc.
