Temperature Sensor Module DS18B20
We have ✅ 21 available of the LB-24-TEMP in our Sydney warehouse.
DS18B20 Digital Temperature Sensor Module!
It has three pins:
GND: This pin is labelled as '-' on the module, it is also called 'GND'. What is 'GND'? In electronics, we define a point in a circuit to be a kind of zero volts or 0V reference point, on which to base all other voltage measurements. This point is called ground or GND.
Out: The DS18B20 temperature sensor uses the 1-Wire protocol, and only requires a single data line. This is the data out pin where the temperature data will be output. Later, we will connect this to a GPIO pin on the micro:bit.
+ : This is connected to 3.3V on the micro:bit.
Voltage is the difference in potential between two points. As it is difficult to talk about voltage without a reference point, we need another point to compare it to.
The Temperature Sensor Module DS18B20 appears in the following collections:
