Temperature Sensor - High Temperature, Waterproof (DS18B20)

This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. 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. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.

Because each DS18B20 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 buildings, equipment or machinery, and process monitoring and control.

Note: The pinout for this sensor is as follows: RED=Vcc BLACK=GND WHITE=SIG

  • 3.0-5.5V input voltage
  • -55°C to +125°C temperature range
  • ±0.5°C accuracy from -10°C to +85°C
  • Waterproof
  • 1 Wire interface
  • Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.
  • Thermometer resolution is programmable from 9 to 12 bits.
  • Electrical performance: no flicker or breakdown within AC 1200V/1S ,within DC 500V the insulation resistance shall be greater than 100MΩ

Wireless Remote Weather Station with micro:bit

May 11, 2020

Monitor the weather without being exposed to it through wireless communication between two micro:bits using the radio blocks! This is useful if your weather station is installed in a location that is difficult to retrieve data from the OpenLog. We will also explore a few different ways to send and receive data.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

  • What is the difference between this and the SEN-11050? The specs seem the same. This is called High Temperature but they both have a max of 125C. Can this tolerate pressure? I want to put it in a water pipe. (I don't expect more than 75 PSi)

    • The sensor itself is the same in both products, the difference is the cable on this one is rated for the full 125C where only the sensor is rated for that on SEN-11050.

      I don't think these will hold up under water pressure, if you're going to subject it to 75PSI you might need to give it a good covering of silicone first just to be sure water doesn't get in.
