Plant soil moisture meter and automatic controller circuit. I like planting trees, because trees are more useful to us.
However, I always have problems with moisture content of soil,Each plant needs water is not as same. Watering or soil moisture is not good. May cause damage to our trees. With these problems, I think the electronic system to solve this problem. For example, to check moisture level of the soil. Infrared Temperature Sensor Module from Dexter Research Center, Inc. The Temperature Sensor Module (TSM) infrared thermometer is the low cost solution for non-contact temperature measurements.
The sensor is integrated with signal conditioning that reliably produces a calibrated temperature output in a plug-and-play package having many options. Monitoring your Air Quality. Automatically measuring and graphing Air Quality with an inexpensive device (Sharp GP2Y1010AU0F Optical Dust Sensor) Copyright 2012, Chris Nafis Check out my latest results with the Grove Shinyei Model PPD42NS Dust Sensor Table of Contents Background With allergies and asthma I'm interested in both the indoor and outdoor air quality.
I heat with a Quadrafire woodstove. There are several citizen group projects that are developing open source equipment (e.g. Monitoring The $290 DC1100 Pro Air Quality is a true Laser Particle Counter with two different size ranges. Arduino Nano IO Shield (SKU: DFR0012) Introduction.
Level-Converter-v10.pdf (application/pdf Object) Logic Level Converter. Description: If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be.
The SparkFun logic level converter is a small device that safely steps down either 5V signals to 3.3V or steps up 3.3V to 5V. GPS datalogging shield for Arduino. Would you like to use your Arduino to create geo-locative art?
Or make a custom GPS device that can log sensor data along with the precise time and location? Perhaps you're looking to make a tracker, or want to make your own geocaching hardware. You are in luck! Linearize optical distance sensors with a voltage-to-frequency converter - 2012-04-19 07. Logger Shield: Datalogging for Arduino. NEW PRODUCT – Proto-Screwshield (Wingshield) kit. February 18, 2011 AT 10:57 am NEW PRODUCT – Proto-Screwshield (Wingshield) kit!
The next generation Proto-ScrewShield is a dual-purpose prototyping shield. Now only does it have a large 0.1″ grid prototyping area but it also extends the Arduino pins to sturdy, secure, and dependable screw terminal blocks. You even get a few bonus terminals for extra GND and four ‘free’ terminals for whatever connections you wish! The stack-able wing design allows you slip this under any shield and still get easy access to the “analog” & “digital” ports of the Arduino. 2.8 TFT Touch Shield for Arduino [2.8] ID: 376 - $59.00. We've discontinued this version of the shield (which was expensive and difficult to make) and replaced it with a version 2: its got a better price, uses way fewer pins, is Mega/Leonardo compatible and has a great touchscreen controller built in.

Back in February, we wrote a post on Analogue to Digital Conversion.
Many people mentioned that it was a bit light and they would like a more advanced tutorial. Well here it is… In this tutorial we add a second analogue input and use the ADC Conversion Complete interrupt. The circuit we are using is similar to what we used last time but has an extra trimpot and uses an ATmega168A microcontroller. The ATmega168 is now obsolete, but its replacement (ATmega168A) is almost identical. The code is pretty simple as you can see below. Because we set the prescaler to 128, it takes 1664-3200 clock cycles to read the analogue input. On line 48 we initiate an AD Converter read.
The interrupt service routine reads in the ADC value and stores it in adc[0] or adc[1]. Return the favour We work hard to write tutorials that we hope you like.
