Field fixed-point observation logger (4) - data storage to the SD card (1)

It uses an SD card to store the acquired data. It is not a difficult thing to hardware.

Material list

Schematic

Capacitor in what is known as a bypass capacitor, it is intended to stabilize the current.
I have used the capacitor 1μF.

Acquisition of the dew point - field fixed-point observation logger (3)

The previous acquisition of temperature and humidity - (2) field fixed-point observation logger you obtained by calculation from the dew point temperature and relative humidity that was acquired in.
Therefore, by changing only the programs, circuits, etc. (2) field fixed-point observation logger - the acquisition of temperature and humidity no different.

Acquisition of temperature and humidity - (2) field fixed-point observation logger

First of all, I want to get the temperature and humidity.

Material list

Data sheet

Schematic

Resistance in what is called a pull-up, because of to keep the correct state signal of the signal line is also.
Capacitor in what is known as a bypass capacitor, it is intended to stabilize the current.
Please check the resistance and capacitance of the capacitor because it is written in the data sheet.

Preparation of Arudino - field fixed-point observation logger (1)

For battery use, Arduino to use the fixed-point observation to use less power consumption "Arduino pro 3.3V 8MHz".

Material list

By using the "FT232RL equipped small USB- serial adapter 3.3V", to connect with USB and PC because it has become only serial connection without a USB port for this Arduino.

I soldered as follows the pin socket for connection to the breadboard and shield.

Field fixed-point observation logger (0) - objectives and targets

projects: Biotope it is inspired by the like, and attempt to create a fixed-point observation logger of the field.
Later, to record where to obtain and price of parts used to be able to re-create.

Purpose

  • To get the temperature of the field (DHT22)
  • To get the humidity of the field (DHT22)
  • I is calculated from the temperature and humidity the dew point of the field
  • To get the surface temperature of the field (LM35DZ)
  • To get the surface temperature of the field (LM35DZ)
  • To get the surface temperature of the field (DS18B20 +)
  • I want to record output in CSV format to SD card each acquired data

Goal

  • Be created in Arduino1.01
  • And a battery power supply, it can be two weeks moving least
  • That the real-time clock is also running on the SD card replacement and battery replacement

Development environment

  • MacBookAir (Lion) or Windows7 (32bit) or WindowsXP
  • Arduino1.01
