DS18B20 Waterproof Temperature Sensor Probe
- DS18B20 Waterproof Temperature Sensor Probe with Thermal Probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface.
DS18B20 Waterproof Temperature Sensor with Thermal Probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface.
The DS18B20 temperature sensor provides 9 to 12-bit temperature readings over a 1-Wire interface, so that only one wire needs to be connected from a central microprocessor.
Dallas DS18B20 One Wire Temperature Sensor is a pre-wired and waterproofed (with heat shrink) version of a 1 Wire DS18B20-compatible sensor.
Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C.
Because they are digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter.
DS18B20 Temperature Sensor Probe work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.
Because each DS18B20 Temperature Sensor Probe contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus.
This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside.
We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor.
Dallas DS18B20 One Wire Temperature Sensor an electronic thermometer which has high accuracy over a wide range . You can locate these thermometer chips up to 100M away from your Arduino.
