This device just sends data about the state of our office to Twitter (mainly because it`s just slightly more relevant than sending the same information about my house). It does however have potential relevance to more biodiversity themed activities, particularly if combined with long range WiFi technologies (which I have written abou

t before: Installing remote WiFi on the Jurassic Coast ). Data collected from a similar device used in conjunction with a malaise trap might start to give clues about the behaviour of the things you collect, to give one example. The device shown below omits the Arduino Ethernet shield which is used to attach the device to the internet. The prototyping board used in the actual device is, for reasons of practicality, an Arduino prototyping shield attached on top of the Ethernet shield. The temperature is measured using an LM35 temperature sensor, and the light measured (imprecisely) using a photoresistor (which we could have calibrated but we just use to detect whether the light is on or off). So it might not be the most useful thing at present, but a ruggedised, battery powered, weatherproof version could have a huge number of potential uses for biodiversity sciences, particularly if combined with other sensors (e. g. a humidity sensor). In addition to the tweeting version (which allows for remote data collection) the Ethernet shield also has a micro SD card reader, allowing for storage of data offline for collection at a later date.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
