Electronic Brick - Ds18b20 1 - Wire Digital Thermometer Module
Electronic Brick - Ds18b20 1 - Wire Digital Thermometer Module

Electronic Brick  Description:

What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.
DS18B20 is a single-bus digital temperature sensor with features of ultra-small size, wide range of applicable voltage and measurable temperature and high resolution, etc. , which can be applied to temperature control, industrial systems, consumer products, thermometers or any thermal measurement system.

DS18B20 Instruction:

Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. The figure below shows a block diagram of DS18B20. The scratchpad memory contains the 2-byte temperature register that stores the datal output from the temperature sensor. In addition, the scratchpad provides access to direct temperature alarm trigger registers (TH and TL) and the 1-byte configuration register. The configuration register allows the user to set the resolution of the temperature-to-digital conversion to 9, 10, 11, or 12 bits. The TH, TL, and configuration registers are nonvolatile (EEPROM), so they will retain data when the device is powered down.
Connect S port of DS18B20 electronic brick to D0 port of Arduino board, and we will use the following program to read register information and temperature value.
DS18B20 Features:
1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock
3. Rotatable detecting direction for better adaption.
