In this instructable I will show you how to make weather station system by yourself. All you need is basic knowledge in electronics, programming and a little bit of time.
This project is still in the making. This is only first part. Upgrades will be uploaded in next one or two months.
So let’s begin
Step 1: Materials
Nearly all needed materials for this project can be bought on online store: DFRobot
For this project we will need:
-Some nylon cable ties
-Li- ion batteries (I used Sanyo 3.7V 2250mAh batteries)
-Waterproof plastic junction box
-Resistors (2x 10kOhm)
Step 2: Modules
For this project I used two different modules.
Solar power manager
This module can be powered with two different supplys, 3.7V battery, 4.5V – 6V solar panel or USB cable.
It has two diffrent outputs. 5V USB output which can be used for supplying Arduino or some other controller and 5V pins for powering different modules and sensors.
- Solar Input Voltage (SOLAR IN): 4.5V~6V
- Battery Input (BAT IN): 3.7V Single cell Li-polymer/Li-ion
- BatteryCharge Current(USB/SOLAR IN): 900mA Max trickle charging, constant current, constant voltage three phases charging
- Charging Cutoff Voltage (USB/SOLAR IN): 4.2V±1%
- Regulated Power Supply: 5V 1A
- Regulated Power Supply Efficiency (3.7V BAT IN): 86%@50%Load
- USB/Solar Charge Efficiency: firstname.lastname@example.orgV 900mA BAT IN
This module is fully compatible with Arduino. It allows you to add mass storage and data logging to your project.
I used it for collecting data from weather station with 16GB SD card.
- Break out board for standard SD card and Micro SD (TF) card
- Contains a switch to select the flash card slot
- Sits directly on a Arduino
- Also be used with other microcontrollers
Step 3: Weather Station Kit
The main component for this project is weather station kit. It is powered by 5V from Arduino or you can also use external 5V supply.
It has 4 pins (5V, GND, TX, RX). TXD data port uses 9600bps.
Weather station kit consist of:
- Wind vane
- Rain bucket
- Sensor Board
- Stainless steel studdle (30CM)(11.81″)
- Component package
It can be used to measure:
- Wind speed
- Wind direction
- Amount of rainfall
It has build in humidity and temperature sensor which can also measure barometric pressure.
Anemometer can measure wind speed up to 25 m/s. Wind direction is displayed in degrees.
More info about this kit and sample code can be found on: DFRobot wiki
Step 4: How to Assemble Weather Station Kit
The assembly of this kit is quite easy but for more info about assembly watch a tutorial on how to assemble this kit.
