Me Temperature Sensor‐Waterproof(DS18B20)
SKU: 11014 Weight: 60.00 Gram
Description:
This is the temperature sensor based on chip DS18B20 consisting of a waterproof
probe and long wire shape, which is perfect for immersive temperature detectionor
detectingg something far away.The DS18B20 provides 9 to 12-bit (configurable)
temperature readings over a 1-Wire interface, so that only one wire (and ground) needs
to be connected from a central microprocessor.
The original one includes three wires inside，we adjusted it into a 3-pinconnector so
that you can use it simply with Makeblock Me Adapter. (there is no soldering required to
connect to our Me BaseBoard just like below picture).
please note that while the sensor is good up to 125°C, the cable which is jacketed in
PVC will be damaged easily, so we suggest keeping it under 100°C.
Features:
Waterproof
Uses 1-Wire interface- requires only one digital pin for communication
Stainless steel tube 6mm diameter by 35mm long
Arduino library for easy programming
Dimensions:
Probe is 6mm in diameter and roughly 50mm long. Overall length
(including wire) is 0.5 meter
Specification
Power supply: 3.0V to 5.5V
Wide temperature range: -55°C to +125°C
High accuracy: ±0.5°C( -10°C to +85°C)
Overview
The Me Temperature Sensor module is a metal tube thermometer with DS18B20 detector.
Featuring strong anti-interference ability and high accuracy, it is covered with waterproof
rubber hose outside and able to measure temperature in the range -55 ~+125 . It can be
connected to the RJ25 Adapter module which is then connected to Makeblock Orion for
temperature measurement.

●
Connecting with RJ25
If you want to connect to a thermometer through the RJ25 port, simply connect it to the RJ25
Adapter module, and then connect the module to Makeblock Orion as follows:
●
Connecting with Dupont wire
When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its SIG
pin should be connected to digital port as follows:
Guide to programming
●
Arduino programming
If you use Arduino to write a program, the library Makeblock-Library-master should be invoked
to control the Me Temperature Sensor-Waterproof.
This program serves to read current temperature through Arduino programming.
The code segment serves to read the readings of Me Temperature Sensor and output the result
to the serial monitor in Arduino IDE with the cycle of 1s.
Upload the code segment to Makeblock Orion, click the Arduino serial monitor and you will see
the running result as follows:
