Flat Blade 125mm Precision Miniature Electronic Side-Cutters with Sprung Jaws
Data Logger Shield with Real Time Clock for Arduino Uno
This Arduino compatible shield allows the logging and storage data from an Arduino project to an SD card.
Having a built in Real Time Clock (RTC) insures data accuracy over long time periods and at times where your project may suffer from power loss. Supplied with a CR1220 lithium battery.
What is the KY-015 DHT11 Module?
The KY015 is a temperature and humidity module for Arduino and other microcontroller projects
KY-015 module has a DHT11digital temperature and humidity sensor and a resistor. The DHT11 uses a thermistor for the temperature sensing and a capacitive humidity sensor along with an internal IC to give a digital output for both temperature and humidity.
Voltage : 3.3 to 5VDC
Humidity range : 20% to 90% @ 5% RH accuracy
Temperature range : 0C to 50C at 2C accuracy
How Can I use the KY-015 Module to monitor temperature and humidity?
Temperature and Humidity Sensor
In this project, we will be building a weather station that can measure both temperature and humidity.
This is what you will need:
First you will nedd to assemble the project. Connect everything together using the wiring diagram bellow for reference.
Connect the KY-015 sensor module to the Arduino
Ground - - - - - - - - - - Ground
A 10KΩ pull-up resistor is built in to the KY-015
Connect your Arduino to the PC and install the above Libraries. If you don’t know how to do this, CLICK HERE and follow the “Installing Arduino Libraries” section.
We can now create the code to get this all working
First, delete the code in the IDE window, then include the aforementioned libraries:
This bit of code imports the DHT library and links it to the sketch.
This bit of code defines which pin is KY015 connected to and sets the type of sensor (KY015 uses DHT11)
This bit of code initialises the sensor
The setup bit of code initialises serial output with baud rate of 115200 and prints DHT11 test! In the console
This bit makes the Arduino wait 2 seconds between measurements
Read humidity from the sensor
Read temperature from the sensor
Print the latest reading in serial monitor
Solderless Female to Female Jumper Leads in a set of 40
This set of coloured female to female jumper leads can be used together or peeled apart into smaller sets or single leads. They are great for prototyping with boards like Arduinos and Raspberry Pi.
With 10 different colours and 4 of each colour, it's easy to keep track for quick fault finding.
Colours: Red, Orange, Yellow, Green, Blue, Grey, Purple, Brown, Black and White
3A DC-DC Step Down Voltage Regulator (Buck Converter)
This tiny step down voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take 4.5V to 28V and lower it to between 0.8V and 20V at up to 3A (output). The voltage is set with the small in built potentiometer.
Voltage in : 4.5V - 28VDC
Voltage out : 0.8V- 20VDC
Switching Frequency : 1 - 1.5MHz
Maximum Output Current : 3A
Dimensions : 22mm x 17mm
